Bruce Levin on "How Not to Conduct a Randomized Clinical Trial" last week Professor Levin took his criticism a step further with a public talk about PACE at Columbia. The talk was called, appropriately enough, “How Not to Conduct a Randomized Clinical Trial.” For the last couple of years, I have been pointing out that PACE has been used at Berkeley as a case study of bad science in epidemiology courses. Now it is legitimately possible to say that it has been presented at multiple major American universities as a case study of bad science. Thanks, Bruce!!!
