“In an analysis published in the Lancet in 2009, Chalmers and Glasziou estimated that there is avoidable waste of 85% of the 100 billion US dollars invested every year in medical research. A follow-up series of papers looking into this problem in preclinical, clinical, and epidemiological research is currently being prepared. Iain Chalmers will present some preliminary findings from this work.” (ScHARR)
