WATERLOO (KWWL) -- Pharmaceutical companies had a hand in about 17% of cancer research published in well-respected medical journals in 2006. This raises major concerns about conflicts of interest.
University of Michigan researchers combed through more than 1500 cancer research studies -- and found that overall -- nearly a third disclosed conflicts of interest. About 12% involved a study author who was an industry employee.
The randomized trials with reported conflicts of interest were more likely to have positive findings.
