TomBAvoider Posted June 14, 2018 Report Share Posted June 14, 2018 By now it's something of a cliche to observe that a ton of studies, including perhaps especially diet related studies, are shoddy and unreliable. Here's another one, plus more evidence that studies in medicine are again questionable: https://www.npr.org/sections/health-shots/2018/06/13/619619302/errors-trigger-retraction-of-study-on-mediterranean-diets-heart-benefits What prompted the Mediterranean diet researchers to soften their language? A persistent British anesthesiologist named John Carlisle. He knew very little about analyzing the details behind clinical trials until a few years ago, when he wrote a letter to an anesthesiology journal bemoaning the fact that his field was polluted by one researcher's data that many suspected were problematic. The journal editor told Carlisle, a practicing anesthesiologist at Torbay Hospital in Torquay, England, to prove it. So Carlisle did. He read up on statistical methods and looked over more than 160 trials by the researcher, Dr. Yoshitaka Fujii, and analyzed how likely it was that the people had been randomized to different treatments. Randomization is part of the gold standard for clinical studies because it reduces the risk of bias and allows researchers to determine cause-effect relationships. Carlisle found the odds were infinitesimally small that Fujii had randomized people properly. Since Carlisle's findings were published in 2012, medical journals have retracted more than 160 papers by Fujii — the most retractions for any one researcher, by a large margin, according to Retraction Watch.
