Just a quick update to the previous post. At the helpful suggestion of Steve Royle, I’ve added a new section to the report which attempts to normalise retractions by journal. So for example, J. Biol. Chem. has (as of now) 94 retracted articles and in total 170 842 publications indexed in PubMed. That becomes (100 000 / 170 842) * 94 = 55.022 retractions per 100 000 articles.This leads to some startling changes to the journals “top 20” list. If you’re wondering what’s going on in the world of anaesthesiology, look no further (thanks again to Steve for the reminder).
