Since 2018, the FDA has required that U.S. clinical trial results be reported to clinicaltrials.gov within a year of trial completion, but this mandate is often ignored. A recent study found that less than half of U.S. trials submitted results to the site by the deadline. Industry-led trials were the most likely to be reported on time.

研究发现临床数据报告不足。

自2018年以来，FDA要求在临床试验完成的一年内将美国临床试验结果报告给Clinicaltrials.gov，但​​这一要求通常被忽略。最近的一项研究发现，在截止日期之前，不到一半的美国试验向该站点提交了结果。行业主导的试验最有可能按时报告。
