OF THE
TIMES
As the new chief of Stanford University's Prevention Research Center, Ioannidis is cementing his role as one of medicine's top mythbusters. "People are being hurt and even dying" because of false medical claims, he says: not quackery, but errors in medical research.Corruption of science: Mass production of redundant, misleading, and conflicted systematic reviews and meta-analyses
Ioannidis describes meta-analyses as being taken over by industry sponsors and concludes that an estimated 3% of all of these reviews may be useful...'Evidence-Based' Medicine: A Coin's Flip Worth of Certainty
Some fields produce massive numbers of meta-analyses; for example, 185 meta-analyses of antidepressants for depression were published between 2007 and 2014. These meta-analyses are often produced either by industry employees or by authors with industry ties and results are aligned with sponsor interests."...
At best such reviews provide the public with misinformation, at worst they can be dangerous.
Case in point: in a 2005 essay, "Why Most Published Research Findings are False," and which is the most downloaded document of all time on PLoS, the Public Library of Medicine's peer-reviewed, open access journal, John P. A Ioannidis explains in detail how "It can be proven that most claimed research findings are false." And that "for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias."Self-destruction of science: Most findings are wrong or useless
A 2015 British Academy of Medical Sciences report suggested that the false discovery rate in some areas of biomedicine could be as high as 69 percent. In an email exchange with me, the Stanford biostatistician John Ioannidis estimated that the non-replication rates in biomedical observational and preclinical studies could be as high as 90 percent.
