In this commentary on Fries and Krishnan's argument that 'design bias' undermines the status of equipoise as the ethical justification for randomised controlled trials, it is argued that their argument is analogous to Bayesian arguments for the use of informative priors in trial design, but that this does not undermine the importance of equipoise. In particular, mismatches between the outcomes of interest to industrial sponsors of research and outcomes of interest to patients and clinicians ensure that in many cases industry-sponsored trials can fail to reflect the reasonable equipoise of working clinicians.
在这篇关于弗里斯和克里希南观点的评论中,他们认为“设计偏差”破坏了均衡作为随机对照试验伦理依据的地位。本文认为,他们的观点类似于在试验设计中使用信息性先验的贝叶斯论点,但这并不削弱均衡的重要性。特别是,研究的行业赞助商感兴趣的结果与患者和临床医生感兴趣的结果之间存在不匹配,这确保了在许多情况下,行业赞助的试验可能无法反映临床医生的合理均衡。
