A statistical procedure for comparing the survival of two or more groups of patients adjusted for normal mortality expectation, i.e. for calculating relative survival, is proposed. The method is shown to correspond to some commonly used procedures for comparing unadjusted survival; it provides an improvement over these procedures in many situations, even when the normal mortality expectations for the patient groups are the same. An example of its use is given.
本文提出了一种统计方法，用于比较两组或多组患者经正常死亡率预期调整后的生存率，即计算相对生存率。结果表明，该方法与一些常用的比较未经调整生存率的方法相对应；在许多情况下，即使患者组的正常死亡率预期相同，该方法也比这些方法有所改进。文中给出了一个使用该方法的示例。
