评估真实世界证据模拟研究对随机试验的可重复性

研究问题
真实世界证据模拟研究能否重复随机试验的处理效应,以及如何在两个研究间评估重复成功并兼顾错误率与功效?
方法与思路
作者比较怀疑性 p 值与两个试验均显著且效应同向的规则,扩展至非劣效试验,并通过反演构造置信区间。
材料陈述的贡献
摘要称怀疑性 p 值可校准至相同第一类错误率而获得更高功效;应用结论大体相似,但显示更多处理效应证据。
阅读关注点
应核对重复成功的统计定义、错误率对应的零假设、样本量和效应量如何进入计算,以及非劣效界值与区间解释。
阅读边界
所给版本为 arXiv 预印本,同行评审或期刊接收未核实;摘要未说明真实世界模拟的混杂控制及功效比较条件。

原文摘要

Background: The standard regulatory approach to assess replication success is the two-trials rule, requiring both the original and the replication study to be significant with effect estimates in the same direction. The sceptical p-value was recently presented as an alternative method for the statistical assessment of the replicability of study results. Methods: We review the statistical properties of the sceptical p-value and compare those to the two-trials rule. We extend the methodology to non-inferiority trials and describe how to invert the sceptical p-value to obtain confidence intervals. We illustrate the performance of the different methods using real-world evidence emulations of randomized, controlled trials (RCTs) conducted within the RCT DUPLICATE initiative. Results: The sceptical p-value depends not only on the two p-values, but also on sample size and effect size of the two studies. It can be calibrated to have the same Type-I error rate as the two-trials rule, but has larger power to detect an existing effect. In the application to the results from the RCT DUPLICATE initiative, the sceptical p- value leads to qualitatively similar results than the two-trials rule, but tends to show more evidence for treatment effects compared to the two-trials rule. Conclusion: The sceptical p-value represents a valid statistical measure to assess the replicability of study results and is especially useful in the context of real-world evidence emulations.
