This brief review presents a nonmathematical description of the methods used to describe the outcome of patient groups when the time to an event such as death or disease recurrence is of interest. Calculation of the product-limit, actuarial and relative survival curves is described and the underlying principles are explained. Two statistical tests frequently used in comparing survival curves (the generalized Wilcoxon and the log-rank or Mantel test) are described and an example of their use is given.
本简要综述对在关注诸如死亡或疾病复发等事件发生时间时，用于描述患者群体结局的方法进行了非数学描述。介绍了乘积限、精算和相对生存曲线的计算方法，并解释了其基本原理。描述了两种常用于比较生存曲线的统计检验（广义Wilcoxon检验和对数秩检验或Mantel检验），并给出了其使用示例。
