Despite European Union rules that require clinical trial reporting, a new survey finds results from more than four of every five studies run by 30 European universities have not been registered, the latest such finding to stir concerns about the impact on health systems and patient care.
Specifically, 83% of 940 clinical trials were missing results on the EU Clinical Trials Register, a clear violation of EU transparency rules, according to a coalition of international health advocacy groups that canvassed the register. They examined reporting performances of 30 European universities that sponsored the largest number of clinical trials. Together, the universities have sponsored 4,575 studies.
