New meta-research suggests many — maybe most — medical research studies are wrong

A disturbing finding emerged from the meta-research overseen by Dr. John P.A. Ioannidis, new chief of Stanford University’s Prevention Research Center: many, perhaps most medical research studies released in the modern era are incomplete, outdated, heavily spun, and often just plain wrong. In addition, he found that while studies that seem to demonstrate the effectiveness of potentially profitable treatments are rushed to publication, studies that find that such treatments are not effective are ‘back-drawered’ — sometimes for many years — in the hope that further study will reverse those findings and vindicate the drugs — and even when they don’t, the delays mean continuing profits for the companies paying for the research and delaying its publication.
