The study, published online in BMC Medicine, said men were 2.45 (95 % CI, 2.05–2.93) times more likely to have been the subject of legal proceedings.
Legal action was defined as disciplinary action by a medical regulatory body, malpractice experience, complaints received by a medical regulatory or healthcare complaints body, a criminal case, or when a paper on the topic did not specify one of the above.
Data from 32 published papers were pooled and analyzed. At first glance, the methods seem reasonable, and the conclusion may even be correct.
But to their credit, the authors mention that the paper has some limitations which, in my opinion, probably invalidate the results.
