Comment, complaint or appeal?
If you wish to comment on the content of a Cochrane Review, Protocol, or Editorial, please follow the guidance on Submitting comments. To submit a comment on any article in the Cochrane Database of Systematic Reviews, click on the ‘Comment on Review’ (or 'Comment on Protocol' or 'Comment on Editorial') button in the right-hand menu on the relevant article, and complete the comment submission form.
The complaint process exists in parallel with the 'comments' process and may be used either if you believe that the comment is of such a serious nature that urgent corrective action is warranted, or if you believe that the usual process has not been satisfactorily managed or resolved. The complaints policy can be found on The Cochrane Library website: https://www.cochranelibrary.com/help/complaints
If you disagee with an editorial decision made about a specific Cochrane Review, protocol for a Cochrane Review or update of a Cochrane Review, please refer to the appeals policy.
