A Big Hip Impingement Scam - The Chinese Lie on FAI

In Zhu, et al. "Conservative therapy versus arthroscopic surgery of femoroacetabular impingement syndrome (FAI): a systematic review and meta-analysis" researchers use statistical tricks to make surgery for femoroacetabular impingement seem better than nonsurgical treatment. When you look closer, however, you'll discover that the paper is built on shoddy statistical analysis and fundamental mistakes that the researchers and the journal editors should have caught. Multiple quality problems plague this paper, and neither the researchers, peer reviewers, or editors caught any of these egregious errors.
