I. POLICIES

The following policies apply to all manuscripts submitted to Obstetrics & Gynecology. The journal follows recommendations from the Committee on Publication Ethics (http://www.publicationethics.org), the International Committee of Medical Journal Editors (http://www.icmje.org), and the Council of Science Editors (https://www.councilscienceeditors.org/); these also guide the journal's response to allegations of scientific misconduct. If the Editors discover or are notified of a serious problem with a published article, the journal will follow the guidelines on retraction published by the Committee on Publication Ethics.1

Articles published in Obstetrics & Gynecology are evaluated by different methods prior to publication. The following article types are evaluated using a double-anonymized peer review process, which means that authors and reviewers do not know each other's identities: Original Research, Research Letters, Case Reports, Systematic Reviews, Narrative Reviews, Clinical Perspectives, Executive Summaries, Consensus Statements, Guidelines, Procedures and Instruments, Personal Perspectives, Junior Fellow Personal Perspectives, Clinical Conundrums, Questioning Clinical Practice, and Clinical Expert Series.

The following article types undergo Editor review only: Editorials, Presidential Address, Announcements, Junior Fellow Essays, Junior Fellow Toolkits, Letters to the Editor, Corrections, and Retractions.

Although Obstetrics & Gynecology is the official publication of the American College of Obstetricians and Gynecologists (ACOG), the Editors make editorial decisions independent of ACOG. The following ACOG publications are not evaluated by the Editors of Obstetrics & Gynecology, and instead undergo committee review as part of ACOG's Practice Activities; they receive final approval from the ACOG Board of Directors: Clinical Practice Guidelines, Clinical Consensus, Committee Statements, Practice Bulletins, Committee Opinions, Obstetric Care Consensus, Technology Assessments, and ACOG Executive Summaries.

Manuscripts are evaluated by peer reviewers who have consented to review for the American College of Obstetricians and Gynecologists' portfolio of journals. Completed reviews submitted in Editorial Manager may be cascaded to an open access journal within the Obstetrics & Gynecology brand for a subsequent publication decision.

A. Author Appeals

The decisions of the Editors are final, except if the authors can demonstrate that the peer review process was flawed (eg, by reviewer bias) or that substantive factual errors were made by the reviewers or Editors. In these cases, authors who receive a rejection letter may appeal the decision within 30 days of receipt of the email notification. All appeals will be discussed during the journal’s weekly Editors’ conference call.

B. Authorship

The role of authorship is reserved for those individuals who meet the criteria recommended by the International Committee of Medical Journal Editors (ICMJE; http://www.icmje.org):2

  1. Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; and
  2. Drafting the work or revising it critically for important intellectual content; and
  3. Final approval of the version to be published; and
  4. Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

All persons who contributed to the work reported in the manuscript, but not sufficiently to be authors, must be acknowledged in a separate paragraph on the title page of the manuscript. All individuals named in the acknowledgments must give written permission to be named. Documentation of that permission should remain in the author’s files unless requested by the Editorial Office. Verification that permission has been obtained from all named persons should be included in the cover letter.

Ghost Authorship

A ghost author is someone who participates in one or more of the following–research, data analysis, or writing of a manuscript–but is not named or disclosed in the author byline or acknowledgments.3 Ghost authorship is prohibited by the journal. Authors must disclose whether any manuscript preparation assistance was received—including but not limited to topic development, data collection, analysis, writing, or editorial assistance—and, if so, who provided and who paid for the assistance (see section V. Manuscript Structure, part A. Title Page).

Group Authorship

If authorship is attributed to a group or collective, there must be at least one individual name included. List the names of the individuals in the group or collective in an appendix, which will be published online. A reference to the online appendix will appear in the print journal.

Number of Authors

For unsolicited submissions, there are no limits to the number of authors that may appear in the byline of an article. However, all authors listed in the byline must meet the criteria recommended by the ICMJE.

Statements about equal contributions, such as co-first authors or co-senior authors, may be considered. Notes in the manuscript describing the degree of author contribution are not permitted. 

C. Clinical Trials

Obstetrics & Gynecology's policies regarding clinical trial registration and data sharing statements are detailed below.

Clinical Trial Registration

Obstetrics & Gynecology complies with the ICMJE requirement that clinical trials be registered in a public trials registry at or before the time of first patient enrollment in order to be considered for publication.4–6 Notably, not all clinical trials are randomized trials (eg, observational studies can be clinical trials if there is an intervention).

Obstetrics & Gynecology follows the U.S. National Institutes of Health (NIH) definition of a clinical trial: “A research study in which one or more human subjects are prospectively assigned to one or more interventions (which may include placebo or other control) to evaluate the effects of those interventions on health-related biomedical or behavioral outcomes."7 The NIH encourages researchers to use the following questions to determine whether a study meets the NIH clinical trial definition:

  1. Does the study involve human participants?
  2. Are the participants prospectively assigned to an intervention?
  3. Is the study designed to evaluate the effect of the intervention on the participants?
  4. Is the effect being evaluated a health-related biomedical or behavioral outcome?

If the answers to 1–4 are all yes, the study is a clinical trial. For more information, see the NIH website, https://www.grants.nih.gov/policy/clinical-trials/definition.htm.

Clinical trials that are not registered at or before the time of first patient enrollment will be rejected. Registries approved by the ICMJE are ClinicalTrials.gov or any registry that is a primary register of the WHO International Clinical Trials Registry Platform (ICTRP; https://www.who.int/clinical-trials-registry-platform).

Provide the trial registry name, URL, and the registration number at the end of the abstract. In the cover letter, the corresponding author must attest to registering the trial and that the protocol they are reporting to Obstetrics & Gynecology is identical to the posted trial and, if not, precisely where and why it varies. Any changes in protocol should also be discussed in the manuscript itself as well as documented on the trial registry website.

Per ICMJE recommendations, the journal “expects authors to ensure that they have met the requirements of their funding and regulatory agencies regarding aggregate clinical trial results reporting in clinical trial registries.8

Data Sharing Statements for Clinical Trials

Obstetrics & Gynecology complies with the ICMJE requirement that manuscripts reporting clinical trials results submitted as of July 1, 2018, must include a data sharing statement. Data sharing statements must indicate the following, per ICMJE8:​

  • whether individual deidentified participant data (including data dictionaries) will be shared;
  • what data in particular will be shared;
  • whether additional, related documents will be available (eg, study protocol, statistical analysis plan, etc.);
  • when the data will become available and for how long; and
  • by what access criteria data will be shared (including with whom, for what types of analyses, and by what mechanism).

Responses to the five bullet points should be provided in a box at the end of the article.

Finally, authors should note that the ICMJE requires clinical trials that began enrolling participants on or after January 1, 2019, to include a data sharing plan in the trial's registration.

Authors' Data Sharing Statement*

  • Will individual participant data be available (including data dictionaries)?
  • What data in particular will be shared?
  • What other documents will be available?
  • When will data be available (start and end dates)?
  • ​By what access criteria will data be shared (including with whom, for what types of analyses, and by what mechanism)?

*Authors should reply to each question. This box appears at the end of the article.


D. Corrections

To submit a request for a correction, please send an email to [email protected].

E. Disclosure of Potential Competing or Conflicts of Interest

At submission, the corresponding author must identify potential competing or conflicts of interest of a financial or other nature in the electronic Copyright Transfer Agreement. This form includes a section on the disclosure of potential conflicts of interest based on the recommendations of the ICMJE, “Uniform Requirements for Manuscripts Submitted to Biomedical Journals” (http://www.icmje.org/conflicts-of-interest/). Authors should err on the side of full disclosure and provide as much information as possible, whether or not they think the disclosure is relevant. Co-authors will receive a link to the Copyright Transfer Agreement by email if the Editors request a revised manuscript.

In addition, on the title page, author(s) must:

  • Identify all sources of financial support of the study, including provision of supplies or services or financial compensation (eg, salary) from a commercial organization.
  • Provide a listing of all sponsor names. Include an explanation of any role the sponsor(s) had in the study design; collection, analysis, and interpretation of data; writing of the report; the decision to submit the report for publication; or a statement that the sponsor(s) had no such involvement.
  • Disclose any financial involvement that could represent potential conflicts of interest for each author.
Editors and Editorial Board
In instances where an Editor or member of the Editorial Board appears as a byline author, the submission website is configured to block the Editor from looking at any information related to the submission. For members of the Editorial Board, the Editorial Office staff manually check to ensure the manuscript is not sent to them for peer review. Additionally, for the Editors, a statement is added to the title page of accepted articles to state that the Editor recused themselves from all stages of the editorial decision-making process.

F. Industry-Sponsored Research

For research-based submissions, Obstetrics & Gynecology follows the Good Publication Practice (GPP3) guideline for manuscripts that report results that are supported or sponsored by pharmaceutical, medical device, diagnostics, and biotechnology companies.9 The GPP3 is designed to help individuals and organizations maintain ethical and transparent publication practices. Adherence to the GPP3 guideline should be noted in the cover letter. The title page should contain all the requirements listed in section V. Manuscript Structure, part A. Title Page.

For perspectives, narrative reviews, and other article types that are not research-based, Obstetrics & Gynecology will decline to consider submissions when any of the authors are directly employed by a pharmaceutical, medical device, diagnostics, or biotechnology company and the manuscript discusses a topic of interest to that company. Financial support and writing assistance for non-research article types by pharmaceutical, medical device, diagnostics, or biotechnology companies will be evaluated on a case-by-case basis.

G. Double-Anonymized Peer Review

As of July 2021, the following submission types are subject to a double-anonymized peer review process:

Original Research, Research Letter, Case Report, Systematic Review, Narrative Review, Clinical Perspective, Executive Summaries, Consensus Statement, Guidelines, Procedures and Instruments, Personal Perspectives, Junior Fellow Personal Perspectives, Clinical Conundrums, Questioning Clinical Practice, and Clinical Expert Series. Double-anonymized peer review means that authors and reviewers do not know each other's identities. The journal's implementation of the double-anonymized peer review system is intended to help minimize potential reviewer bias. Prior to July 2021, the journal used a single-anonymized peer review process. Single-anonymized peer review means that reviewers know the identity of the authors, but the authors do not know the identities of the reviewers.

Authors should carefully read section V., Manuscript Structure, for specific directions.

H. Institutional and Ethical Approval

All studies should follow the principles set forth in the Helsinki Declaration of 1975, as revised in 2013, and manuscripts should be approved by the necessary authority before submission. Applicable studies should be reviewed by an institutional review board (IRB).10 This review should be documented in your cover letter as well in the Methods section, with an explanation if the study was considered exempt. Insert a sentence in the Methods section stating that the study was approved or why it was deemed exempt from approval. In all cases, the complete name of the IRB should be provided in the cover letter.

During consideration of a manuscript, it may become necessary to examine original source documents such as signed consent forms, IRB minutes, research data books or logs, and statistical calculations. If the Editor requests any such material, and the author is unable or unwilling to produce it, the manuscript will be withdrawn.​

I. Open Access

Authors of accepted articles have the option to pay a fee to allow perpetual unrestricted online access to their published article to readers globally, immediately upon publication. This choice has no influence on the peer review and acceptance process. An information sheet is available at http://links.lww.com/LWW-ES/A48. The cost for publishing an article as open access can be found at https://www.wkauthorservices.editage.com/open-access/hybrid.html.

Open access articles will be freely available to read, download, and share from the time of publication. Authors retain their copyright for all articles they opt to publish open access. Each author must complete and submit the journal's Copyright Transfer Agreement. After acceptance, the corresponding author will then sign the License to Publish form, where they will then own the copyright but grant Wolters Kluwer Health (WKH), the journal's publisher, a license to publish the article and identify itself as the original publisher.

Obstetrics & Gynecology publishes most open access articles under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs 4.0 (CC BY-NC-ND 4.0) license, which allows readers to disseminate and reuse the article, as well as share and reuse of the scientific material. It does not permit commercial exploitation or the creation of derivative works without specific permission from the journal. To view a copy of this license, visit http://www.creativecommons.org/licenses/by-nc-nd/4.0/legalcode.

The CC BY (Gold route) and CC BY-NC (Green route) licenses are available only to authors who received funding from entities who require these licenses, such as RCUK and Wellcome Trust. Please contact the Editorial Office ([email protected]) if you have a question about which open access license we may offer based on the funding for your manuscript.

Compliance With Research Funding Agency Accessibility Requirements

A number of research funding agencies now require or request authors to submit the postprint (the article after peer review and acceptance but not the final published article) to a repository that is accessible online by all without charge. As a service to our authors, WKH identifies to the National Library of Medicine (NLM) articles that require deposit and transmits the postprint of an article based on research funded in whole or in part by the National Institutes of Health, Howard Hughes Medical Institute, or other funding agencies to PubMed Central. The Copyright Transfer Agreement provides the mechanism. Wolters Kluwer Health ensures that authors can fully comply with the public access requirements of major funding bodies worldwide. Additionally, all authors who choose the open access option will have their final published article deposited into PubMed Central.

It is the responsibility of the author to inform the Editorial Office and/or WKH that they have funding in their submitted Copyright Transfer Agreement. Wolters Kluwer Health will not be held responsible for retroactive deposits to PubMed Central if the author has not completed the proper forms.

J. Patient Privacy and Consent

​Some article types—such as Case Reports, Procedures and Instruments, and Personal Perspectives—may contain descriptions of individual patients. In these cases, a signed consent form must be obtained from each patient described in the manuscript and retained by the authors. The same rule applies to an image of a patient shown (in part or whole) in a photograph or video. It is preferable to give patients the opportunity to read the manuscript and/or view the images or video containing their image. A sample form is available online at http://edmgr.ovid.com/ong/accounts/release.pdf.

Please state in the cover letter with your submitted manuscript that you have obtained a signed consent form (eg. written consent) and that this form will be filed with your records. Unless the Editorial Office requests that you do so, please do not submit upload the signed consent form to the journal in Editorial Manager, or send the form by email.

In some cases, non-patients (eg, a physician or nurse) are visible in a photograph or video. In these cases, the Editorial Office will request and collect consent forms from those people.​

K. Permissions

Tables and figures should be original. The use of borrowed material (eg, lengthy direct quotations, tables, or figures) or material adapted or modified from another source is strongly discouraged.

If borrowed material is used, written permission of the copyright holder must be obtained by the authors and credit to the original source indicated. Both print and electronic rights must be obtained. Authors must include this documentation with the submitted manuscript (eg, by uploading scanned copies of forms or by emailing the forms to the Editorial Office). Authors are responsible for any associated permission fees.​

L. Plagiarism

Plagiarism is the act of presenting “the act of using another person's words or ideas without giving credit to that person."11 All potentially acceptable manuscripts are screened for plagiarism by using the CrossCheck/iThenticate software, which compares the manuscript to material uploaded to CrossCheck's own database, articles published on PubMed, and text appearing on the Internet. Manuscripts that are to be rejected usually are not checked for plagiarism unless a reviewer has raised concerns about the manuscript.

Please note that CrossCheck/iThenticate also checks for self-plagiarism or text recycling. Authors should be careful to rework and/or cite text from their previously published works.

If the Editors discover plagiarism in a submitted or published article, the journal will follow the guidance of the Committee on Publication Ethics for addressing this type of misconduct.1,12,13

M. Prior Publication

Original submissions will be considered for publication with the understanding that they are contributed solely to Obstetrics & Gynecology. If any of the material in the manuscript is submitted or planned for publication elsewhere in any form (including electronic media), or if the information appeared in a previous publication, identify the other submission in the cover letter and include a copy of that publication. This does not apply to documented materials from other sources such as quotations, figures, and tables. Failure to comply with this stipulation may lead to a judgment of redundant publication.

Preprint Servers

The journal will consider a manuscript that has been posted on a community preprint server. Please provide details about the preprint server posting in your cover letter and title page and include the DOI. Note that the peer reviewed, edited, and typeset version of the manuscript may not be deposited to a preprint server.

Presentation at Meetings

The journal will consider a complete report that follows presentation at a scientific meeting (eg, abstract, oral presentation, or poster). Researchers who present their work at such a meeting may discuss their presentations with the media. However, offering more detail about the study than was presented in the abstract or poster (eg, providing additional data or copies of tables and figures) is prohibited.14 Indicate such presentations in your cover letter and on the title page by providing the full name of the meeting, as well as the city, state, and dates. If your submission to the journal could conflict with a future scientific meeting presentation, please notify the Editorial Office so that journal does not unintentionally break the meeting's embargo.

Previous Submission to Obstetrics & Gynecology

If a version of the manuscript has previously been submitted for publication to Obstetrics & Gynecology, authors must include a point-by-point response to the comments from the previous round of peer review. Manuscripts that are resubmitted without a cover letter addressing the previous peer reviewers' comments will be returned to the author.​

N. Race and Ethnicity in Studies

For studies that report on the topic of race or ethnicity or include it as a variable, authors must provide an explanation in the manuscript of who classified individuals' race, ethnicity, or both, the classifications used, and whether the options were defined by the investigator or the participant. In addition, the reasons that race and ethnicity were assessed in the study also should be described (eg, in the Methods section and/or in table footnotes). Race and ethnicity must have been collected in a formal or validated way. If it was not, it should be omitted. Authors must enumerate all missing data regarding race and ethnicity as in some cases, missing data may comprise a high enough proportion that it compromises statistical precision and bias of analyses by race.

Use “Black" and “White" (capitalized) when used to refer to racial categories. The nonspecific category of “Other" is a convenience grouping/label that should be avoided, unless it was a prespecified formal category in a database or research instrument. If you use “Other" in your study, please add detail to the manuscript (and the tables, if applicable) to describe which patients were included in that category.

List racial and ethnic categories in tables alphabetically.

An Equity Rubric (https://journals.lww.com/greenjournal/Pages/specialissue.aspx) and guidelines on how to report race and ethnicity (https://edmgr.ovid.com/ong/accounts/Race_and_Ethnicity.pdf) in articles submitted to Obstetrics & Gynecology are available for authors and reviewers to use.​

O. Reporting Guidelines

Obstetrics & Gynecology supports initiatives aimed at improving the reporting of health research. For manuscripts that require reporting guidelines, a checklist or explanation in the cover letter must accompany the submission. The manuscript will be returned to the author if this information is not included in the initial submission. We ask authors to use the following guidelines when drafting their manuscripts:

Obstetrics & Gynecology does not require use of other reporting guidelines. However, authors may wish to search http://www.equator-network.org for guidelines for other types of studies to facilitate complete, transparent, and accurate reporting of their work.

Authors should address all items recommended by the guidelines. Where this is not possible, please provide an explanation in the text to give a transparent account of your study. If there are items on the checklist that you cannot attest to, please itemize these in your cover letter with an explanation.​

Guidelines for Reporting Multivariable Prediction Models

The Editors strongly suggest referring to “Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD): Explanation and Elaboration.27 Often authors use a nomogram (Figure 7 in reference 26; doi: 10.7326/M14-0698), which is a useful visual aid for showing the various model inputs, but we also encourage use of a visual display of a calibration curve (Figure 8 in reference 27; doi: 10.7326/M14-0698). This figure allows the reader to see the relationship of observed versus predicted probabilities along the spectrum of probabilities from the data, along with confidence intervals for those prediction estimates. An added feature is the display below the x-axis of the relative counts of adverse versus non-adverse outcomes. Alternatively, those could be displayed (similar to survival analysis graphs) with numerical counts of adverse versus non-adverse outcomes at the intervals referred by the graph. The advantage to this level of detail is that it would convey to the reader the strength of association at various model scores, along with their relative uncertainty, reflecting how many data were available at various cut points.

Guidelines for Reporting Cost-Effectiveness Analyses

Cost-effectiveness analyses should be reported in accord with the recommendations of the Second Panel on Cost-Effectiveness in Health and Medicine.28 The panel recommends that cost-effectiveness analyses report two reference case analyses, one based on a societal perspective and one based on a health care sector perspective. Health effects are most commonly reported in terms of quality adjusted life years (QALYs) while the health care sector reference case may be summarized as an incremental cost-effectiveness ratio (ICER).

Guidelines for International Classification of Diseases (ICD) and Current Procedural Terminology (CPT)

Transparency regarding data sources for observational studies is critical for understanding the patient population to which the results may apply. In addition to STROBE, the Editors extend this effort by incorporating additional requirements for transparency for studies using International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes through the requirement of RECORD.24 This is important, given the increased complexity of ICD-10 compared to ICD-9 coding and some difficulties with crosswalking between them. The Editors strongly encourage authors to read two publications related to this topic and to incorporate the recommendations in them. Utter et al29 articulate issues related to ICD-10 coding. Benchimol et al24 describe the RECORD extension to the STROBE statement, which includes 13 items that add nuance to observational studies using routinely collected health data.

Authors are encouraged to do the following in their manuscript:​

  1. State which ICD-10-CM/PCS codes or algorithms were used as Supplemental Digital Content.
  2. Use both the diagnosis and procedure codes.
  3. Verify the selected codes apply for all years of the study.
  4. Conduct sensitivity analyses using definitions based on alternative codes.
  5. For studies incorporating both ICD-9 and ICD-10-CM/PCS codes, the Discussion section should acknowledge there may be disruptions in observed rates related to the coding transition and that coding errors could contribute to limitations of the study.29 The limitations section should include the implications of using data not created or collected to answer a specific research question, including possible unmeasured confounding, misclassification bias, missing data, and changing participant eligibility over time.24
  6. The journal does not require that the title include the name of the database, geographic region or dates, or use of database linkage, but this data should be included in the abstract.
  7. Include RECORD items 6.3 and 7.1, which relate to transparency about which codes, validation method, and linkage were used to identify participants and variables collected.

P. reVITALize Data Definitions

Standard obstetrics and gynecology data definitions have been developed through the reVITALize initiative,30–31 which was convened by the American College of Obstetricians and Gynecologists and the members of the Women’s Health Registry Alliance. Obstetrics & Gynecology adopted the use of these definitions, and they are available at https://www.acog.org/practice-management/health-it-and-clinical-informatics/revitalize-gynecology-data-definitions (gynecology) and https://www.acog.org/practice-management/health-it-and-clinical-informatics/revitalize-obstetrics-data-definitions (obstetrics). 30–31 If using the reVITALize definitions is problematic, please contact the Editorial Office at [email protected].

Q. Survey Response Rates

The Editors rarely consider a survey study with a response rate of less than 60%. A response rate below 60% increases the risk of a sampling error that can result in biased survey estimates. The journal infrequently makes exceptions for outstanding studies, and only when non-responders have been well-characterized and there is clear evidence that nonresponse is not linked to the information sought in the survey. The authors need to demonstrate that respondents were representative of all those who were eligible to take the survey.

R. Transparent Peer Review

In order to increase transparency around the peer review process, the journal has implemented the following policies and procedures for accepted articles:

  • The dates of submission, revision, and acceptance will be published at the end of the article.
  • The peer reviewers' and Editor's comments to the author, along with the authors' responses to these comments, will be published as supplemental digital content to the online version of the article. Reviewers will not be identified by name.

Authors can opt out of having their responses published if they wish to do so. However, even if the authors decline to have their responses published, the reviewer and editor comments will be posted online.

S. Portable Peer Review

Obstetrics & Gynecology offers “portable peer review,” an expedited peer review process on a very selective basis for high-priority submissions. This process entails the Editors using completed peer reviews from another journal. In cases of portable peer review, the Editors will make an initial decision within 14 days based on those previous peer review comments, review from an Editorial Board member, and review by the journal’s Editors.  If you are interested in submitting a manuscript for portable peer review, please contact the Editorial Office at [email protected]. Submissions that are not selected for portable peer review may be submitted through the standard peer review process. The journal will not post the reviewer comments from other journals as supplemental digital content in the Peer Review History.

T. Fast-track Online Publication

For timely topics of importance to clinical care, the Editors will consider offering online fast-track publication, following peer review and formal acceptance. To be considered, please submit a presubmission inquiry to the Editors at [email protected].

U. Cascade to O&G Open

As of January 2024, any author who submits to Obstetrics & Gynecology may receive an offer to transfer their work for consideration in O&G Open , ACOG’s open access companion journal. Following peer review, authors who are selected for the transfer process will receive an email from the Editorial Office. Authors who agree to transfer their work will receive additional guidelines for updating their submission prior to completing the formal submission in O&G Open’s Editorial Manager site . Authors have 14 days to respond to the transfer offer, and then will have 21 days to submit an updated manuscript for consideration. Authors who agree to transfer their manuscript will be responsible for paying the article processing charge  if the manuscript is accepted for publication. Questions about this process should be directed to [email protected].

Causal Language

Causal language is reserved for results of randomized controlled trials. Avoid using language such as “effects of" or “impact on" when “association with" is meant.​​

Gender-Inclusive Language

The journal follows ACOG’s Statement of Policy on Inclusive Language (https://www.acog.org/clinical-information/policy-and-position-statements/statements-of-policy/2022/inclusive-language). Please be mindful of using gendered descriptors in your manuscript. Instead of “women” and “females,” consider using the following:
•    “Individuals”
•    “Patients”
•    “Participants”
•    “People” (not “persons”)
•    “Women and transgender men”
•    “Women and gender-expansive patients”
•    “Women and all those seeking gynecologic care”

In secondary analyses or database studies, please retain the language used by parent study or database source for consistency.

Person-First Language

The journal uses person-first language. Please review your submission to make sure to center the person before anything else. Examples include:
•    “Patients with obesity” instead of “obese patients”
•    “Women with disabilities” instead of “disabled women”
•    “Participants with HIV” instead of “HIV-positive participants”
•    “Women who are blind” instead of “blind women”
•    “People with diabetes” instead of “diabetics”
•    “Women with hypertension” instead of “hypertensives”

Propensity Score Matching

In studies that are not randomized trials, often the groups being compared have baseline differences in some characteristics. Some of these characteristics may plausibly affect the probability of the adverse outcome(s). Often, mathematical modeling tools such as adjustment of an odds ratio or relative risk are used to mitigate the effect of those baseline differences. However, a problem can arise when the number of adverse events is low in relation to the number of variables used in the adjustment model. Basically, there can be insufficient information to adjust for the variables at hand, making the resulting model “overfitted." That is, the model output contains more parameters than is justified by the data. The model may conform to the data at hand, but it is not reliably generalizable.

There are several ways to address this limitation. One may be able to design the study, based on the presumed rates of adverse outcomes, to have sufficient sample sizes to allow for several potential adjustors. Alternatively, the adjustment model could be supplemented with a matching algorithm (eg, propensity score matching) to create cohorts that are statistically similar at baseline. We encourage authors to address this potential limitation both in the design and analysis phases of their studies, believing this approach would strengthen their submission.

While no method can adequately substitute for a randomized trial, we suggest that if Authors corroborate their multivariable regression analysis with a matching algorithm, then the reader might be more likely to accept the conclusions as valid.


Presentation of Data

All percentages should be expressed to one decimal place (for example, 11.1%. Do not use whole numbers for percentages. Odds ratios, relative risks and hazards ratios as well as confidence intervals should be expressed to 0.01 precision (for example 1.81; 95% CI, 1.02-2.92).


P Values vs Effect Size and Confidence Intervals

While P values are a central part of inference testing in statistics, when cited alone, often the strength of the conclusion can be misunderstood. In your abstract, manuscript, and tables, the preferred citation should be in terms of an effect size, such as odds ratio or relative risk or the mean difference of a variable between two groups, expressed with appropriate confidence intervals. When such syntax is used, the P value has only secondary importance and often can be omitted or noted as footnotes in a Table format. Putting the results in the form of an effect size makes the result of the statistical test more clinically relevant and gives better context than citing P values alone. When included, P values should not exceed three decimal places (for example, “P=.001”.  If the P value is lower, then should format as “P​<.001”.


Data Sets Extrapolated to Entire U.S. (or Other) Population

When analyzing data from large data sets (eg, National Inpatient Sample), it is important to show the reader the relationship between the survey sample size and the counts as extrapolated (weighted) to the entire U.S. population. Many of our readers may not be familiar with the complexities of the survey method, but need context to see the difference in scale between the actual counts vs those for the entire U.S. population. To that end, the authors should include a flow diagram showing the actual counts at the top layer, then the weighted counts at the bottom. For an example, see Figure 1 in Obstet Gynecol 2021;138:738‒46; doi: 10.1097/AOG.0000000000004577.

In addition, authors should include two versions of their statistical analysis: one based on the actual counts and the second on the weighted counts. If there are multiple secondary outcomes, then these two versions could be in supplemental material. For the main conclusions, both versions (original and weighted) should be in the main text.

The purpose of including both analyses is to demonstrate for the reader how the confidence intervals vary with the respective sample sizes and to what extent the survey method adjusted for bias (that is, whether the point estimates materially changed).


A. Original Research

An Original Research article is a full-length report of an original clinical or basic investigation. Length should not exceed 3,000 words (Table 1). References should not exceed 30. Figures or tables are limited to five, total. Original Research articles must follow the reporting guideline applicable to the study type (see I. Policies, O. Reporting Guidelines, for more information). 

1) Abstract: Original Research articles should have a structured abstract using the following headings:

  • Objective: Main question, objective, or hypothesis (single phrase starting with, for example, “To evaluate" or “To estimate" [never start with “To determine"]).
  • Methods: Study design, participants, outcome measures, and, in the case of a negative study, statistical power.
  • Results: Measurements expressed in absolute numbers and percentages, and when appropriate indicate relative risks or odds ratios with confidence intervals and level of statistical significance; any results contained in the abstract should also be presented in the body of the manuscript, tables, or figures.
  • Conclusion: Directly supported by data, along with clinical implications. Do not include statements such as “further research is needed."
  • Funding Source: This heading is needed only for manuscripts with industry funding. This paragraph contains an abbreviated list of the funders.

2) Manuscript Sections: Organize Original Research articles in a manner similar to their structured abstract.

  • Introduction: Orients the reader to the problem(s) addressed by the report, preferably in one page or less, and clearly states the hypothesis or objective of the research. Avoid a detailed literature review in this section.
  • Methods: States the type of study conducted and describes the research methodology in sufficient detail so that others could duplicate the work. This section should address IRB approval (see I. Policies, H. Institutional and Ethical Approval). Identify methods of statistical analysis and, when appropriate, state the basis (including alpha and beta error estimates) for their selection. Cite any statistical software programs used in the text. In most cases, express P values to no more than three decimal places. Indicate your study's power to detect statistical difference. Authors of clinical trials should include a data sharing statement in a box at the end of the article (see I. Policies, C. Data Sharing Statements for Clinical Trials).​
  • Results: Presents the findings in appropriate detail. Tables and figures may be used, but take care to minimize duplication between the text and tables or figures. Clinical studies (observational or randomized) must include a flow diagram describing patient accrual or inclusion. Authors should report outcome data as both absolute and relative effects, since information presented this way is much more useful for clinicians. Actual numbers and percentages should be given in addition to odds ratios or relative risk. When comparing the cost of two procedures, please express the outcome of the comparison in U.S. dollar amounts.​
  • Discussion: Begin with a description of what your study found in relation to the purpose or objectives as stated in the Introduction. Address the primary outcome first, followed by the secondary outcomes (if appropriate). Describe rather than repeat results given earlier. The findings should be compared to previous studies with explanations in cases where they differ, although a complete review of the literature is not necessary. Comment on the limitations of your study. Clearly state the importance of these findings to clinicians and actual patient care. Although some degree of speculation as to the importance of the observations is permissible, avoid making conclusions unrelated to the data presented. Primacy claims purporting that your study is the first or largest of its type should either be supported by a description of your search strategy or omitted. A final summary is not necessary, as this information should be provided in the abstract and the first paragraph of the Discussion. Although topics that require future research can be mentioned, it is unnecessary to state that “further research is needed."

B. Research Letter

The Research Letter is a concise, focused report of original research (including pre–clinical research, subanalyses, or updates of previously published research, small studies, or pilot studies). Length should not exceed 750 words (Table 1). Figures or tables are limited to two, total. References should not exceed 10. Supplemental digital content is allowed. Submitted Research Letters undergo the same external peer review as other article types, and the policies outlined in the journal's Information for Authors likewise apply.

  9. Include manuscript word count. Word count includes text (see manuscript sections for each article type), but excludes the title page, abstract, precis, tables, boxes, figures, figure legends, reference list, and supplemental digital content.

B. Manuscript

The first page of the manuscript file should contain the title of the manuscript and the précis, for use in the Table of Contents. The précis is a single sentence of no more than 25 words that states the conclusion(s) of the report (ie, the bottom line). The précis should be similar to the abstract’s conclusion. Do not use commercial names, abbreviations, or acronyms in the précis. Continuous line numbers should start on this page.

C. Abstract

The abstract should appear after the précis. All information in the abstract should be consistent with the information in the text, tables, or figures. Avoid use of commercial names in the abstract. See Section II., Article Formats, for more information on how to format the abstract based on article type.​

D. Text

The main body of the article appears after the abstract. See Section II., Article Formats, for more information on how to format the body based on article type. Continuous line numbering should be used throughout the text. Authors should also keep the following style considerations in mind:

Abbreviations and Acronyms

Only standard abbreviations and acronyms are allowed. A selected list is available online at https://edmgr.ovid.com/ong/accounts/abbreviations.pdf. Abbreviations and acronyms cannot be used in the title or précis. Abbreviations and acronyms must be spelled out the first time they are used in the abstract and again in the body of the manuscript.

Commercial Names

The commercial name (with the generic name in parentheses) may be used once in the body of the manuscript; use the generic name at each mention thereafter. Commercial names should not be used in the title, précis, or abstract.

E. References

Use references found published in peer-reviewed publications that are generally accessible. References should be numbered consecutively in the order in which they appear in the text (note that references should not appear in the abstract) and listed double-spaced at the end of the manuscript.​

​     The preferred method for identifying citations is using superscript, but citations that are cited on the line within parentheses are also acceptable.

     Please do not use the footnote or endnote functionality in Microsoft Word. You may use reference management software (eg, EndNote) to organize and style your references. However, note that the specific style for Obstetrics & Gynecology may not appear in these software programs.
 
     Unpublished data, forthcoming or in-press items, and personal communications are not acceptable as references. Please include a website reference with package inserts. Include a DOI for all journal articles. All website references should have an “Accessed" date.

     Authors are responsible for the accuracy of all references. See the “Reference Formatting Instructions" at https://edmgr.ovid.com/ong/accounts/ifa_suppl_refstyle.pdf for the journal's current style for different reference types. 

F. Tables

Authors are strongly encouraged to become familiar with the format of tables published in Obstetrics & Gynecology by reviewing recently published tables. The publisher formats wide tables so that they appear on one printed page in the published article. The journal does not print tables in “landscape” orientation, nor do we print tables across two pages. If a table is too wide for one printed page, the first column will repeat on the next page with the remaining columns. For more information on how to format your tables for the journal, see the tables checklist online at http://edmgr.ovid.com/ong/accounts/table_checklist.pdf.

G. Figures

At first submission, please submit your figures with their accompanying figure legends within the manuscript. If your manuscript is peer reviewed and deemed potentially acceptable for publication, you will be asked to submit your figures as individual files separate from the manuscript file in Editorial Manager. Source files, EPS or PDF files, or higher resolution TIFFs may be requested. Art that is low resolution, digitized, or downloaded from the Internet will not reproduce well. Graphs created in Microsoft Word, PowerPoint, or Excel should be submitted as .doc or .docx, .xls or .xlsx, or .ppt or .pptx files. Original, high-resolution, or editable files are needed. Unacceptable art may be redrawn or removed from the article.

H. Figure Legends

Each figure should have an accompanying legend. For purposes of the initial submission and peer review process, please include each legend with its figure on a separate page of the manuscript. A sentence or two is usually sufficient. Identify any abbreviations or symbols in the legend. In the case of photomicrographs, provide magnification and stain data.

VI. SUPPLEMENTAL DIGITAL CONTENT

Authors may submit supplemental digital content to enhance their article's text. All supplemental digital content will be reviewed by the Editors and editorial staff before posting. Supplemental digital content may include the following types of content: text documents, graphs, tables, figures, graphics, illustrations, audio, PowerPoint, and video. Content should be original and not previously published or posted elsewhere.

When submitting supplemental digital content online to Editorial Manager, the digital files should be uploaded along with your other submission items.

Supplemental digital content that comprises text, tables, or figures should be cited consecutively in the text as “Appendix 1," “Appendix 2," etc. Do not number supplemental text, figures, or tables separately—order them in the way they are cited at first mention. In addition, any references cited in appendixes should be added to a separate References list in the appendixes file. For video files, provide a legend that includes the title of the video, brief summary of the content, and the name of the creator(s). Authors should ensure that patients are not identifiable in the supplemental digital content unless they obtain written consent from the patients and document that they have obtained consent in the cover letter submitted with the manuscript. To ensure a quality experience for those viewing supplemental digital content, the journal's publisher suggests that authors submit supplemental digital files no larger than 10 MB each. The exceptions to this rule are audio or video files, which are acceptable up to 100 MB. See the box for a list of acceptable file types for supplemental digital content.

Supplemental Digital Content (SDC) File Types

Text files and tables: .doc, .docx, .odt, .xls, .xlsx, .ppt, or .pptx
Figures, graphics, and illustrations: .tif, .eps, .ppt, .jpg, .pdf, or .gif
Audio files: mp3 or .wav (.wav not acceptable if the file exceeds 10 MB)
Video files: wmv, .swf, .flv, .mov, .qt (.qt not acceptable if the file exceeds 10 MB), .mp4, .avi, .mpg, .mpeg, or .m4v


VII. WHAT TO EXPECT AFTER SUBMISSION

After submitting a manuscript to Editorial Manager, the corresponding author can expect to receive notification of receipt by email within 2 business days. Approximately 40% of submitted manuscripts are rejected without formal peer review. The remainder are sent to peer reviewers.

The Editors use reviewer comments as well as their own evaluation to arrive at an initial disposition—accept, decline, or revise. The journal's goal is to arrive at the disposition within 6 weeks of submission.

Authors who are invited to submit a revised version of their manuscript will receive the reviewers' critiques, the Statistical Editor's comments, and the Editor's analysis. This action should not be interpreted as a commitment to accept the manuscript. Authors are asked to submit the revised manuscript within 21 days; requests for extension of the deadline may be granted.

The revision is evaluated by the Editor and may be sent back to the reviewers to see if the concerns have been addressed satisfactorily. Additional revisions may be necessary before the manuscript is considered for publication. 

Upon acceptance, the manuscript is processed for publication. The usual length of time between acceptance and publication is approximately 1 month.

The corresponding author will receive an email requesting that he or she review the page proofs online. The author(s) should respond to all queries and check the proofs carefully. If comments are not received within 48 hours, it is the policy of the journal to proceed with publication.

Authors of accepted articles should consult the article sharing guidelines provided by Wolters Kluwer Health, the journal's publisher (see https://shop.lww.com/journal-permission), as well as the website “How Can I Share It" (https://www.howcanishareit.com/) for guidance on how, when, and where they can share each version of their work. Wolters Kluwer endorses the STM “Voluntary principles for article sharing on scholarly collaboration networks,"32 which enables and encourages the collaboration necessary to advance research.

Authors are encouraged to work with their institution's press office to promote their article following embargo. The College's Communication Department is able to provide embargoed articles to press and answer any questions surrounding embargo ([email protected]).
