Clinical trial rule is widely ignored

Many researchers are ignoring a 2005 requirement that they register proposed clinical trials in a government database as a condition for publishing their results in medical journals. And the journals are publishing the papers anyway, a new study reveals. The study, a review of 323 articles published last year in leading medical journals, found that only 147 of the clinical trials–45.5 percent–were properly registered before the end of the trial in a way that clearly stated the main outcomes being assessed. Even among the articles that were registered, almost a third had discrepancies between the outcomes described in the registry and the ones ultimately reported.
