# Instructions to Authors

### Instructions to Authors

SLEEP Advances is an official publication of the Sleep Research Society (SRS).

## Scope

SLEEP Advances is a peer-reviewed, online-only, gold open access journal publishing high-quality and replicable basic, translational, and clinical research in sleep and circadian science. The goals of SLEEP Advances are to disseminate timely developments and advances that reflect the diversity of sleep and circadian science and to offer quick, objective, and straightforward peer review.

• Submissions will be rapidly processed with a result and feedback given to authors
• Accepted papers are immediately available on the SLEEP Advances website for public viewing.
• All articles are available free to the public after publication on PubMed Central and the journal website.

Noteworthy manuscripts are promoted to various national and local media via the journal's public relations staff.

## Online Submission Information

All materials are submitted and edited electronically using ScholarOne. To submit an original manuscript, review article, editorial, or letter to the editor, please go to ScholarOne Manuscript Central. Complete instructions for the electronic submission process can be found on that site.

## Open Access Publication Fee Information

SLEEP Advances authors will publish their paper under the Oxford Open Initiative; whereby, for a charge, their paper will be made freely available online immediately upon publication. Sleep Research Society members receive a discount on these charges. Please visit the following link for membership information: https://www.sleepresearchsociety.org/membership/

RCUK/Wellcome Trust funded authors publishing in SLEEP Advances can use the Creative Commons Attribution license (CC BY) for their articles.

All other authors may use a Creative Commons Attribution Non-Commercial license (CC BY-NC).

## Categories of Manuscripts

The following types of manuscripts will be considered:

### Original Articles

Original Articles present original research findings in the fields of sleep/circadian medicine and sleep/circadian science, broadly defined. There is no minimum or maximum length for Original Articles, but reductions in manuscript length (including numbers of figures and/or tables) may be required as an outcome of peer review. The submission of incomplete data sets, partial cohorts, or pilot data is discouraged. SLEEP? does not publish Original Articles that describe individual patient-based case reports or case series that lack a comparator or control group and thus lacks analytical components for hypothesis testing.

### Review Articles

Review articles are critical evaluations of material that has already been published. An author of a review article should consider the progress of current research toward clarifying a problem. A review paper should summarize previous investigations in order to inform the reader of the state of current research; identify relations, contradictions, gaps, and inconsistencies in the literature; and suggests the next step or steps in solving the problem. The review section may also include summaries of symposia presentations at national or international meetings.

### Editorials and Letters to the Editor

Editorials have a maximum word length of 1,500 words plus as many references as needed, and may include one figure or table. Letters to the editor should be no more than 1,000 words plus references, which should be limited to a maximum of ten, and may include one figure or table. Replies to Editorials or Letters to the Editor may be solicited by the Editor in Chief and published together in the same journal issue. A limited number of case reports will be considered as Letters to the Editor.

SRS membership number(s) must be stated during online submission for all eligible authors.

## Essential Elements of Manuscript Submission

### Guidelines for Statistical Analysis

Accurate use of statistical methods is a prerequisite for publication in SLEEP Advances. Statistical methods must be rigorous irrespective of the type of publication and reporting of statistical findings must be accurate and complete. Editors can request an expert statistical review of all submissions, particularly if there are methodological questions or concerns. SLEEP Advances follows the same guidelines as the journal SLEEP.

### Ethics of Investigation

Authors should specify within the manuscript whether ethical standards were used in their research. If results of an experimental investigation in human or animal subjects are reported, the manuscript should describe the approval by an institutional review board on human or animal research, and the appropriate informed consent procedures for human subjects. If approval by an institutional review board is not possible, then information must be included indicating that clinical experiments conform to the principles outline by the Declaration of Helsinki.

### Privacy and Informed Consent

Authors must omit from their manuscripts and figures any identifying details regarding patients and study participants, including patients’ names, initials, Social Security numbers, or hospital numbers. If there is a possibility that a patient may be identified in text, figures, photos or video, authors must obtain written informed consent for use for in publication of print, online, and licensed uses of SLEEP Advances, from the patient or parent or guardian and provide copies of the consent forms to SLEEP Advances . In such cases where the patient may be identified, authors must indicate that they have obtained informed consent in their manuscript. In addition, all authors are responsible for ensuring that their manuscript and figures comply with the Health Insurance Portability and Accountability Act (HIPAA).

## Publication Ethics

Authors should observe high standards with respect to publication ethics as set out by the Commission on Publication Ethics (COPE) and International Committee of Medical Journal Editors (ICMJE). Falsification or fabrication of data; plagiarism, including duplicate publication of the authors’ own work without proper citation; and misappropriation of work are all unacceptable practices. Cases of ethical misconduct are treated very seriously and will be dealt with in accordance with COPE guidelines.

The US Office of Research Integrity defines scientific misconduct and includes these behaviors:

• Falsification of data: ranges from fabrication to deceptive reporting of findings and omission of conflicting data, or willful suppression and/or distortion of data.
• Plagiarism: The appropriation of the language, ideas or thoughts of another without crediting their true source and representation of them as one’s own original work.
• Improprieties of authorship: improper assignment of credit, such as excluding others, misrepresentation of the same material as original in more than one publication, inclusion of individuals as authors who have not made a definite contribution to the work published, or submission of multi-authored publications without the concurrence of all authors.
• Misappropriation of the ideas of others: an important aspect of scholarly activity is the exchange of ideas among colleagues. Scholars can acquire novel ideas from others during the process of reviewing grant applications and manuscripts. However, improper use of such information can constitute fraud. Wholesale appropriation of such material constitutes misconduct.
• Violation of generally accepted research practices: serious deviation from accepted practices in proposing or carrying out research, improper manipulation of experiments to obtain biased results, deceptive statistical or analytical manipulations, or improper reporting of results.
• Material failure to comply with legislative and regulatory requirements affecting research: including but not limited to serious or substantial, repeated, willful violations of applicable local regulations and law involving the use of funds, care of animals, human subjects, investigational drugs, recombinant products, new devices, or radioactive, biological or chemical materials.
• Inappropriate behavior in relation to misconduct: this includes unfounded or knowingly false accusations of misconduct, failure to report known or suspected misconduct, withholding of information relevant to a claim or misconduct and retaliation against persons involved in the allegation or investigation.

SLEEP Advances also consider misconduct to include redundant publication and duplicate publication, lack of declaration of competing interests and of funding/sponsorship, and other failures of transparency.

### Managing allegations of misconduct

The Editorial Staff take seriously all possible instances of misconduct. If an editor has concerns that a submitted article describes something that might be considered to constitute misconduct in research, publication or professional behavior, the editorial team will discuss the case in confidence.

If the case cannot be resolved by discussion with the author(s) and the Editor-in-Chief still has concerns, the case may be reported to the appropriate authorities. If, during the course of reviewing an article, an editor is alerted to possible problems (for example, fraudulent data) in another publication, the editor will immediately alert the Editor-in-Chief.

Readers who suspect misconduct in a published article are encouraged to report this to the Editor–in-Chief. Cases of research publication misconduct may be referred to COPE in an anonymized format if further guidance is required.

## Disclosures

### Authorship

All authors listed on the manuscript should have contributed significantly to the design or implementation of the experiment or the analysis and interpretation of the data. Any other individuals who contributed to the experiment or the writing of the manuscript should be listed in the Acknowledgment section. During online submission, the corresponding author must certify on behalf of all authors that they have read and approved the submitted version.

### Dual Authorship

Co-first authorship and co-senior authorship may be indicated on the title page of the manuscript with a statement that the two first authors have contributed equally to the manuscript. If co-authorship is indicated, it is the understanding of the Editors that all authors of the manuscript agree to this designation.

Dual corresponding authorship may be indicated on the title page of the manuscript and both authors will appear on the correspondence line on the final article. However, only one can be considered the corresponding author in the online manuscript submission system; thus, only the corresponding author designated in the system will receive automated messages, such as editors’ decisions and page proofs.

### Authorship and "Umbrella" groups

Many large collaborative studies are organized under a group name that represents all the participants. All articles must have at least one named individual as author. Authors who wish to acknowledge the umbrella group from which the data originate should list the authors of the article, followed by "on behalf of the [GROUP NAME]". The members of the group should be listed individually in the acknowledgments section, and if correctly presented will ultimately be listed in Medline as “collaborators.”

For further guidelines on authorship, please refer to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals [PDF], formulated by the International Committee of Medical Journal Editors.

### Originality

During online submission, the corresponding author must certify on behalf of all that, with the exception of publication in a preprint server, their manuscript (i) is a unique submission, (ii) has not been submitted and is not being considered for publication by any other source in any medium, and (iii) has not been published, in part or in full, in any form. In the acknowledgements section of the manuscript authors must describe all prior publications or postings of the material in any form of media. Failure to divulge previous publications is a violation of the Ethical Guidelines for Publication of Research and will result in a placement of notice of unethical practice in the publication.

### Conflict of Interest

Conflict of interest exists when an author has financial or other interests that could be reasonably perceived to inappropriately influence his or her judgment. Because of this, authors must disclose potentially conflicting interests so that others can make judgments about such effects. Authors may consult with the Editor-in-Chief regarding material to be included in this disclosure (by email via jnoel@srsnet.org ). Such consultation will be held in strict confidence.

The Disclosure Statement is a manuscript requirement that applies at the time of submission, to all the authors of a paper and to all categories of submissions. Papers that do not include a Disclosure Statement will be returned to authors for correction. The Disclosure Statement includes two statements: Financial arrangements or connections that are pertinent to the submitted manuscript (or none) and Non-financial interests that could be relevant to the submitted manuscript (or none).

## Reuse of Oxford University Press Material

In order to reproduce any third party material, including tables, figures, or images, in an article authors must obtain permission from the copyright holder and be compliant with any requirements the copyright holder may have pertaining to this reuse. When seeking to reproduce any kind of third party material authors should request the following:

• non-exclusive rights to reproduce the material in the specified article and journal;
• print and electronic rights, preferably for use in any form or medium;
• the right to use the material for the life of the work; and
• world-wide English-language rights.

It is particularly important to clear permission for use in both the print and online versions of the journal, and we are not able to accept permissions which carry a time limit because we retain journal articles as part of our online journal archive.
Further guidelines on clearing permissions

## Preprint Repositories and Prior Publication

SLEEP Advances allows the submission of preprints. Preprints are manuscripts that have not been submitted to a journal for full peer review, have not been copyedited or typeset, and have been deposited to a recognized repository such as bioRxiv. Authors submitting preprints to SLEEP Advances must inform the editorial office at the time of submission that the manuscript is a preprint and guarantee that it does not infringe any subsequent copyright or license agreement. Upon final publication, authors must add a link from the preprint to the final published article.

Also at the time of submission, authors must describe all prior publications or postings of the material in any form of media that is not a preprint repository. Abstracts or posters displayed for colleagues at scientific meetings need not be reported. These non-preprint occurrences will be evaluated by the Editor-in-Chief to determine if the postings are material enough to constitute prior publication.

Failure to divulge previous publications is a violation of the Ethical Guidelines for Publication of Research and will result in a placement of notice of unethical practice in the publication.

## Open Access Licenses and Fees

SLEEP Advances is a fully (gold) open access journal. After the manuscript is accepted the corresponding author will be required to accept and pay for a mandatory license to publish agreement.

## Citations within Text/Reference List

SLEEP Advances uses the American Medical Association 10th Edition style guide. There is no limit on the number of references for original articles or reviews. The reference section should begin a new page at the end of the text.

A standard bibliography program such as EndNote or Reference Manager may be used. We cannot guarantee that citation/reference software will match all SLEEP Advances author guidelines.

Accuracy of reference data is the responsibility of the author. Failure to initially comply with the journal’s style requirements may result in manuscripts returned to authors for correction and may potentially delay publication.

#### Citations within the Text

• Each reference should be cited in the text, tables, or figures in consecutive numerical order by means of Arabic numerals placed in brackets and outside periods and commas and inside colons and semicolons.
• When three or more references are cited at one place in the manuscript, a hyphen should be used to join the first and last numbers of a series.
• Commas should be used without spaces to separate other parts of a multiple-reference citation.

#### Sample citations within the body of a paper

Multi-part figures: Assemble the parts into one file rather than sending several files. Do not submit Fig 1 a, Fig 1 b, Fig 1 c. Instead submit Fig 1 a-c.

Symbols and abbreviations should be defined within the figure or in the figure caption or together in a key.

Type within figures must be legible in the final pdf. Avoid the use of italic and bold unless necessary.

#### Permissions

Authors are responsible for obtaining full permission to publish figures for which they do not hold the copyright. Proof of this permission is required prior to publication. If a figure has been previously published, a citation to the original publication and/or necessary attribution should be included in the figure caption as required by the copyright holder of the figure.

Photographs of subjects in which the individual is identifiable require a signed model release.

### Table Guidelines

Tables must not duplicate data reported in the manuscript text or figures.

Each table must be self-contained and comprehensible without referring to the manuscript

Each table should begin a new page

Tables may be included in the manuscript document following the Reference List and/or Figure Captions.

Alternatively tables may be submitted together in a separate file with the File Name: Tables.

Tables must be cited, consecutively, in the manuscript text.

Tables should be numbered using Arabic numerals (e.g., Table 1, Table 2 etc.)

Tables should be formatted to fit the width of the page (use landscape when necessary.)

Footnotes should be marked with superscript lowercase letters or symbols and not marked with numbers (Arabic or Roman numeral). All footnotes should be fully expanded in the table caption.

Type within tables must be legible in the final pdf. Avoid the use of italic and bold unless necessary.

Authors are responsible for obtaining full permission to publish tables that have been previously published. Permission from the original publisher must be obtained and all necessary attribution should be included in the table’s caption.

### Supplemental Materials

While discouraging indiscriminate use of supplemental materials, some forms of data (videos and large datasets, explanations of data sources, details of computational algorithms) may be appropriately presented as supplemental material. Supplemental material must be directly relevant to the conclusions offered in the main text but non-essential for reader understanding. Information that is essential to understanding the article must not be provided as supplemental material.

No comments or critiques of supplemental material will be considered for publication in SLEEP Advances. Supplemental materials, including data sets, are not copyedited by SLEEP Advances. It is the responsibility of the authors to ensure that all files are checked carefully.

#### Supplemental Material Guidelines

Supplementary material should be referenced to in the text of the main manuscript.

Supplementary material may be submitted together in one file (inclusive of text, captions, list, tables, figures) or as several separate files.

A list of captions for supplementary tables and figures must be included.

There are no restrictions for file extension type or figure resolution.

Supplementary tables need not be in an editable format but they should be formatted to fit the width of the page.

Captions and file names should be numbered sequentially using Figure S1, Table S1, Data set S1 etc.

### Video Guidelines

Videos should be provided in .mp4 format.

Provide a Word file containing succinct captions for of the videos.

Captions and File names should be numbered sequentially using Video 1, Video Captions List etc.

Releases signed by persons who appear in any video must be provided with the submission of videos. SLEEP Advances will not publish any video where persons can be identified without suitable permission forms on file.

### Dataset Guidelines

Large datasets should only be submitted when necessary to support a manuscript’s conclusions, when solicited by Editors/Reviewers, or if the authors feel that the publication of the dataset is critical to advancing research in the field. These should be submitted as an Excel spreadsheet, which will be made available for download. Authors have the option of providing a link to large data sets and hosting them on their own website.

### Review Process

The Editor-in-Chief and/or Associate Editors first determine if a submitted manuscript is suitable for review and publication. Manuscripts selected are then sent for peer-review to reviewers who are selected based on their expertise related to the particular manuscript. After reviews are submitted, a recommendation of accept, reject or revise (for further consideration) is made by the Associate Editor to the Editor-in-Chief, who makes the final decision. A decision of reject is final and no resubmission of the same or largely the same paper is permitted.

Manuscripts are reviewed with due respect for the author's confidentiality. At the same time, reviewers also have rights to confidentiality, which are respected by the editors. SLEEP Advances uses single-blind peer review: reviewers will see author names, but authors will not see reviewer names, unless they choose to self-identify within their review content. The editors ensure both the authors and the reviewers that the manuscripts sent for review are privileged communications and are the private property of the author.

During online submission, authors may suggest the names of potential reviewers to invite and/or exclude.

### Revisions

If a manuscript is returned to the author(s) for revisions, all resubmissions must follow the Instructions for Submitting a Manuscript and include the following:

Revisions must include a response document. The author’s response must state each editor and reviewer comment (including line number) followed by the author’s response using a point-by-point format, detailing the action(s) taken on all comments and concerns. Two versions of the revised manuscript must be prepared: a clean manuscript and a marked manuscript showing changes, using highlights, colored text or the Track Changes feature etc. (do not show deletions).

The deadline for submission of a revised manuscript needing major revisions is 60 days from the date of the notice. For minor revisions, the deadline for resubmission is 30 days. There is no guarantee that a revised manuscript will be accepted for publication.

## Notice of Acceptance

### Submission of First Look Production Files

Accepted manuscripts are subject to a final submission from authors of production quality files. Manuscripts are carefully checked by the editorial office to be sure all files meet the submission guidelines for the manuscript, tables, figures and supplementary material. Once the files are approved they are sent to the Production Team for copyediting.

## Plagiarism Review

SLEEP Advances carefully monitors accepted papers for plagiarism. If plagiarism is detected at acceptance or during any part of the peer review process, the manuscript may be rejected.

We define plagiarism to include: literal copying - reproducing a work word for word, in whole or in part, without permission and acknowledgment of the original source; paraphrasing - reproducing someone else's ideas while not copying word for word, without permission and acknowledgment of the original source; substantial copying - copying images, or data from other sources; text-recycling - reusing substantial amounts of text from your own previous publications.

Any text contained in a manuscript that is directly copied from another source must be placed within quotation marks and the original source must be properly cited. If a paper captures the essence of a previously published work, that work should be cited. If any paraphrasing is included, the source must be properly referenced and the meaning intended by the source must not be changed. All works that may have inspired a study’s design or manuscript structure must be properly cited.

For published papers where plagiarism is detected, we reserve the right to issue a correction or retract the paper, whichever is deemed appropriate. We reserve the right to inform authors' institutions about plagiarism detected either before or after publication.

All accepted manuscripts are subject to manuscript editing for conciseness, clarity, grammar, spelling and SLEEP Advances style. After acceptance all manuscripts will be copyedited. The copyedited version will be sent to the corresponding author for review and approval and returned to Oxford University Press. Once the manuscript is scheduled for publication, the corresponding author will be notified as to the assignment of the manuscript to an issue and page proofs will be sent to the corresponding author. These proofs will be emailed as a PDF file and authors will be expected to return their corrections or approval of these proofs within the timeframe given in the email. It is the authors’ responsibility to keep their account in ScholarOne current or to notify the Journal Editorial Office (SLEEPadvances.editorialoffice@oup.com) of any changes in contact information after a paper has been accepted.

## Accepted Papers

In order to provide readers with access to new scientific developments as early as possible, all manuscripts accepted by the Editor in Chief will be available online prior to being published. Accepted manuscripts are posted as received - without editing or formatting by the publisher. The layout and appearance of each article will change when published in SLEEP Advances.

All papers appearing in SLEEP Advances, including online Accepted Papers, are copyrighted by the SRS. No paper in whole or in part may be used in any form without written permission from the SRS.

Advance Articles are published online soon after they have been accepted for publication, in advance of their appearance in a journal issue and before copyediting and typesetting. Appearance in Advance Articles constitutes official publication, and the Advance Article version can be cited by a unique DOI (Digital Object Identifier). When an article appears in an issue, it is removed from the Advance Articles page.
