Since 2007 there is a legal obligation to report results of registered clinical studies in a timely manner. Now more than 10 years later, how is compliance with this regulation? Problematic, according to a recent publication in the Deutsche Ärzteblatt (Richter-Kuhlmann, E., Deutsches Ärzteblatt | Jg. 117 | Heft 31–32 | 3. August 2020, A1492-A1497). Especially academic centers lag behind when it comes to the reporting of study results. The Cochrane foundation Germany published an analysis in The Lancet, stating that out of 4.200 clinical studies in the (US-based) study register ClinicalTrials.gov , for only around 40% results have been communicated.
