CEPI5215 Chap.9 Reviewing a Medical Paper
Reviewing a Medical Paper
Peer reviewers advise editors by evaluating contribution, validity, reporting and ethical issues. This chapter begins with expertise, time, conflicts and confidentiality before acceptance, then uses layered reading to distinguish major scientific concerns from minor presentation points.
A constructive report summarises the manuscript, prioritises numbered comments, explains why each issue matters and states what adequate repair would require. The recommendation should follow the documented evidence and journal criteria. Review quality depends on proportionality. A fatal validity problem, a limitation requiring narrower interpretation and a stylistic preference should not receive equal weight.
Explicit prioritisation helps authors allocate revision effort and helps editors understand whether the manuscript can become reliable.

- Major comment
- A concern affecting validity, interpretability, ethics or essential reporting.
- Minor comment
- A local clarity or presentation point that does not change the central scientific judgment.
- Confidentiality
- The obligation not to share or use unpublished manuscript information without permission.
- Recommendation
- The reviewer’s proportionate advice to the editor based on the documented report and journal criteria.
Reviewing a Medical Paper FAQ
When should a review invitation be declined?
Decline promptly when the topic or method is outside your competence, the deadline is unrealistic, or a conflict prevents independent evaluation. Disclose uncertain relationships to the editor rather than deciding privately that they do not matter.
What makes criticism constructive?
Identify the specific manuscript issue, explain its consequence for validity or understanding, and state what information or revision would address it. Comment on the work rather than the authors and distinguish requirements from personal preferences.
Should ethical concerns be sent only to the editor?
Specific suspected misconduct may need confidential communication under journal procedure, but ordinary scientific concerns should also be stated clearly enough for authors to respond. Avoid public accusation and provide the factual basis without conducting an unauthorised investigation.
Can a reviewer involve a colleague?
Only through the journal’s authorised process. Ask the editor before sharing confidential material, identify any co-reviewer as required and ensure conflicts and contributions are disclosed. Informal forwarding breaches the manuscript’s confidentiality.
Should reviewers correct every language error?
No. Identify representative patterns and explain when language prevents scientific appraisal. Major review effort belongs to validity, reporting and inference. Detailed copyediting is inefficient when the journal may require substantive revision or decline the paper.
How should suspected misconduct be described?
Document the specific observation and communicate it confidentially to the editor under journal procedure. Avoid definitive accusation without investigation, do not contact third parties independently and keep the manuscript confidential while the authorised process assesses it.
What should a reviewer do when a paper is outside the journal scope?
Explain the scope mismatch to the editor and still identify any central scientific concern needed for a fair decision if the review was undertaken. Do not demand unrelated expansion simply to force fit. The editor, not the reviewer, makes the final venue decision.
Assessment move
Read the manuscript in layers. On the first pass, capture the question, design and main claim. On the second, test participants, variables, analysis, flow and results. On the third, inspect interpretation, displays, references and clarity. Draft major comments in priority order with consequence and requested evidence, then add only useful minor points.
Remove hostile language and demands that redesign a sound study into your preferred project. Finally read the major comments beside the recommendation; the decision should be predictable from the report. Draft the review away from the submission form first. Use headings for summary, major comments and minor comments, and number every actionable point.
For each major comment, add one sentence explaining the consequence for validity or interpretation. Remove requests that are merely your preferred design, and check whether proposed analyses are possible with the collected data. Before submitting, verify that confidential comments do not contradict what authors are allowed to see and that the recommendation follows the report.
