Scientists are routinely cherry-picking the results of clinical trials so that they can present the findings that they want, a study by academics at Oxford University shows. The research, which assessed the published results of more than 100 scientific trials, also found that inconvenient findings were often not disclosed to the public. In several cases, the stated purpose of the trial was altered as it progressed so that acceptable findings, rather than inconvenient results, could be published.The manipulation, which contravenes official guidelines on reporting medical research, was uncovered by academics at Oxford University, led by Dr An-Wen Chan, a researcher on clinical medicine.
