In this methodology editorial, the problem of censored survival (or time-to-event) data in clinical research is discussed. In case of censored observations, part of the observation time for some participants in a study is unobserved, which means that measures such as an average survival time cannot be calculated. Instead, censored survival time should explicitly be accounted for in the analysis of a study, for example using the Kaplan-Meier method. Implications of censoring and how to deal with it in the analysis of a study or when reading a research paper are discussed.

向左看，向右看：临床研究中的审查。

在这篇方法论社论中，讨论了临床研究中生存（或事件时间）数据的审查问题。在审查观察的情况下，研究中某些参与者的部分观察时间未被观察到，这意味着无法计算平均生存时间等指标。相反，在研究分析中应明确考虑删失生存时间，例如使用 Kaplan-Meier 方法。讨论了审查的影响以及如何在研究分析或阅读研究论文时处理它。
