Submitting a paper to a peer-reviewd journal after putting it on medRxiv
Most journals allow this, probably pretty much all of them. If you look at a journal's Guidelines for Authors, they should normally state that this is fine (occasionally it is probably elsewhere but this information should be given on the journal's website). For example, &quot;Statistics in Medicine&quot;'s guidelines say &quot;Statistics in Medicine will consider for review articles previously available as preprints. Authors may also post the submitted version of a manuscript to a preprint server at any time. Authors are requested to update any pre-publication versions with a link to the final published article.&quot;
I'm not aware of specific rules for peer review though - I do realise that &quot;double blind&quot; doesn't really mean &quot;double blind&quot; in this case, but what can they do? (Some journals got rid of double blind peer review because authors could be identified in too many cases too easily anyway, this being one of the reasons.)
