Hazard ratios can be approximated by data extracted from published Kaplan-Meier curves. Recently, this curve approach has been extended beyond hazard-ratio approximation with the capability of constructing time-to-event data at the individual level. In this article, we introduce a command, ipdfc, to implement the reconstruction method to convert Kaplan-Meier curves to time-to-event data. We give examples to illustrate how to use the command.
风险比可以通过从已发表的Kaplan-Meier曲线中提取的数据来近似估计。最近，这种曲线方法已不仅限于风险比近似，还具备在个体层面构建事件发生时间数据的能力。在本文中，我们介绍了一个命令ipdfc，用于实现将Kaplan-Meier曲线转换为事件发生时间数据的重建方法。我们给出示例来说明如何使用该命令。
