All unpublished manuscripts are confidential documents. If we invite you to review an article please do not discuss it even with a colleague: if you would like to pass it on to someone else to review please email firstname.lastname@example.org first.
We ask reviewers to sign their reports and declare any competing interests on any manuscripts we send them. Reviewers advise the editors, who make the final decision (aided by an editorial manuscript committee meeting for some articles, including original research).
For research papers, The BMJ has fully open peer review. This means that every accepted research paper submitted from September 2014 onwards will have its prepublication history posted alongside it on thebmj.com.
This prepublication history comprises all previous versions of the manuscript, the study protocol (submitting the protocol is mandatory for all clinical trials and encouraged for all other studies at The BMJ), the report from the manuscript committee meeting, the reviewers’ signed comments, and the authors’ responses to all the comments from reviewers and editors (read more in this editorial).
If you experience any adverse event arising from open peer review, or would like to tell us your views, please email email@example.com.
We provide a thank-you email once your review is complete, and a free one-year online subscription to bmj.com. We are not able to provide any additional documentation regarding your review.
As a reviewer you will be advising the editors, who make the final decision (aided by an editorial committee for all research articles and most analysis articles). We will let you know our decision. Authors - and readers too, if the paper is accepted and published - will see your signed report, so please do not make any comments that you are not prepared to stand by publicly. Even if we do not accept an article we would like to pass on constructive comments that might help the author to improve it.
Authors can now nominate other BMJ Journals that they would like their manuscript to go to automatically if it is rejected by the first journal. The system also passes on editors' comments and peer reviewers' reports relating to that manuscript, to facilitate the review process at the next BMJ Journal. This means that your review might be read by other editors within BMJ (the publishing group) in due course.
The BMJ's peer reviewers do not have to fill in standard appraisal forms. But we do ask all reviewers to consider this general guidance:
When you provide your review via our online editorial office we will ask you to declare any competing interest that might relate to the article.
Before writing your review you may find it helpful to browse our resources for authors, advice on The BMJ's article types, our transparency policy, and our training materials for peer reviewers. Patients are asked to review our articles from the patient perspective and it may be helpful to also see their training materials.
Please give detailed and constructive comments (with references, whenever possible) that will both help the editors to make a decision on the article and the authors to improve it.
Not all of these points will be relevant for non-research articles. Please use your discretion about the above list when reporting on other types of article.
Some types of article need more specific appraisal, and you may find it useful to look at our checklists.
