Reviewer Guidelines

How to peer review for World Journal of Surgery

The reviewer report should comprehensively critique the submission and consist of much more than a few brief sentences. World Journal of Surgery does not require a specific structure for reports, however, a suggested format is:

• Summary
• Major issues
• Minor issues

We encourage reviewers to help authors improve their manuscript. The peer review report should give constructive analysis to authors, particularly where revisions are recommended. Where reviewers do not wish authors to see certain comments, these can be added to the confidential comments to the Academic Editor.

While expectations vary by discipline, some core aspects that should be critiqued by reviewers may include:

• Are the research questions valid?
• Is the sample size sufficient?
• Is there necessary ethical approval and/or consent and was the research ethical?
• Are the methods and study design appropriate for answering the research question?
• Do the experiments have appropriate controls?
• Is the reporting of the methods, including any equipment and materials, sufficiently detailed that the research might be reproduced?
• Are any statistical tests used appropriate and correctly reported?
• Are the figures and tables clear and do they accurately represent the results?
• Has previous research by the authors and others been discussed and have those results been compared to the current results?
• Are there any inappropriate citations, for example, not supporting the claim being made or too many citations to the authors’ own articles?
• Do the results support the conclusions?
• Are limitations of the research acknowledged?
• Is the abstract an accurate summary of the research and results, without spin?
• Is the language clear and understandable?

To help authors receive timely reviews, reviewer reports should be submitted via the manuscript tracking system on or before the agreed deadline. Reviewers should contact World Journal of Surgery team if they are unable to meet the deadline so that an alternative date can be arranged.

We encourage reviewers to focus their peer review reports on objectively critiquing the scientific aspects of the submission, including the soundness of the methodology and whether the conclusions can be supported by the results. Comments may also be given on novelty and the potential impact of the research work. At the end of their review, we ask reviewers to recommend one of the following actions:

• Publish Unaltered
• Consider after Minor Changes
• Consider after Major Changes
• Reject: Manuscript is flawed or not sufficiently novel

However, it is important to note that the overall decision will be made by the Academic Editor.

Reporting guidelines

World Journal of Surgery does not mandate the use of reporting guidelines by authors. However, we encourage reviewers to use relevant reporting guidelines to help assess the research article. The EQUATOR Network provides clinical guidelines, while FAIRsharing list clinical and general science guidelines. We particularly encourage the use of:

• CONSORT for randomized controlled trials
• TREND for non-randomized trials
• PRISMA for systematic review and meta-analyses
• CARE for case reports
• STROBE for observational studies
• STREGA for genetic association studies
• SRQR for qualitative studies
• STARD for diagnostic accuracy studies
• ARRIVE for animal experiments

Publication ethics

World Journal of Surgery does follow the guidelines of Publication Ethics (COPE). Read the COPE Ethical Guidelines for Peer Reviewers for information on best practice in peer review.

Confidentiality

Manuscripts under peer review should be strictly confidential. Reviewers must not share manuscripts or discuss their content with anyone outside the peer review process.

Reviewers may, on request, consult with colleagues from their research group trusting that the confidentiality of the manuscript is maintained. Reviewers should first contact World Journal of Surgery or the Academic Editor handling the manuscript and note the name of the colleague(s) in the ‘Comments to the editor’ section of their report.

Reviewers will be anonymous to the authors unless they choose to disclose their identity by signing the review report.

Conflicts of interest

Reviewers should decline to review a submission when they:

Reviewers must declare any remaining interests in the ‘Confidential’ section of the review form, which will be considered by the editor.

Reviewers must declare if they have previously discussed the manuscript with the authors.

Reviewers are encouraged to comment on authors’ declared conflicts of interest. If there are concerns that authors have not fully disclosed financial, institutional, commercial, personal, ideological, or academic interests, this should be raised in the reviewer report.
