Last week, JAMA issued some unusual notices, letting readers know they should use caution when reading an editorial and letters associated with now-retracted articles by a bone researcher in Japan. The notices — for papers by Yoshihiro Sato, now up to 14 retractions — remind readers not to heed the results of the now-retracted papers, … Continue reading JAMA tells readers: “Caution advised.” Here’s why.
A sweeping analysis of more than 5,000 papers in eight leading medical journals has found compelling evidence of suspect data in roughly 2% of randomized controlled clinical trials in those journals.
