目的评估随机临床试验作者是否传达了他们使用替代结局的事实,并讨论其有效性。设计队列研究。六大综合医学期刊。参与者2005年和2006年发表的使用替代物作为主要结局的随机临床试验。在626项已发表的随机临床试验中,109项(17%)使用替代物作为主要结局。在这些试验中,62项(57%,95%置信区间47%至67%)明确报告主要结局是替代结局。只有38(35%,26%至45%)也讨论了替代品的有效性。结论:只有大约三分之一的随机临床试验的作者使用替代品作为主要结果充分报告了替代品。需要更好的报告。
Objective To assess if authors of randomised clinical trials convey the fact that they have used surrogate outcomes and discussed their validity. Design Cohort study. Setting Six major general medical journals. Participants Randomised clinical trials published in 2005 and 2006 that used a surrogate as a primary outcome. Results Of 626 published randomised clinical trials, 109 (17%) used a surrogate as a primary outcome. Of these trials, 62 (57%, 95% confidence interval 47% to 67%) clearly reported that the primary outcome was a surrogate. Only 38 (35%, 26% to 45%) also discussed the validity of the surrogate. Conclusion Only about one third of authors of randomised clinical trials that used a surrogate as a primary outcome reported adequately on the surrogate. Better reporting is needed.
