Erren TC, Erren M, Shaw DM. Peer reviewers can meet journals' criteria for authorship. BMJ 2013;346:f166
Should some reviewers be credited as authors? Accurate interpretation of evidence in medicine requires accurate evidence regarding the role of reviewers. In principle, some contributions by reviewers may justify credit for authorship under the International Committee of Medical Journal Editors (ICMJE) criteria. No journals seem to specify how to acknowledge advice from reviewers who contributed substantially to the final paper, and a few even discourage such acknowledgements. It may also be necessary for them to declare any potential conflicts of interest, whether theoretical or financial.
