生存分析和Cox回归中,生存曲线最后交叉,如何衡量治疗效果?

2017-05-12 MedSci MedSci原创

Cox回归是生存分析的常用工具,它有两大优势,一是可以给出衡量效果大小的效应指标HR(Hazard Ratio),另外就是可以同时调整多个变量,便于筛选危险因素或校正混杂。但是任何统计模型都要满足一定的前提假设才可以使用,否则可能得出错误的结论。对于Cox回归,它假定HR值不随时间变化,即我们所说的比例风险假定(Proportional Hazard Assumption)。HR随时间变化,意味着

Cox回归是生存分析的常用工具,它有两大优势,一是可以给出衡量效果大小的效应指标HR(Hazard Ratio),另外就是可以同时调整多个变量,便于筛选危险因素或校正混杂。但是任何统计模型都要满足一定的前提假设才可以使用,否则可能得出错误的结论。对于Cox回归,它假定HR值不随时间变化,即我们所说的比例风险假定(Proportional Hazard Assumption)。HR随时间变化,意味着治疗的效果在用药后的不同时间段不同。如果忽略PH假定,用Cox回归得到的HR值衡量治疗效果,首先会掩盖治疗效果的真实特性,另外HR的解释也会遇到困难。PH条件不满足的情况非常多见,例如图1所示研究[1]。我们可以看到,两条生存曲线最后交叉,这说明PH条件不成立。(关于判断PH条件是否成立的方法我们将在其他文章中介绍,需说明的是,曲线不交叉不代表PH条件一定成立)在进行Cox回归之前,应该先进行PH条件的检验。PH条件成立则计算HR衡量治疗效果。但如果检验结果显示PH不成立时该如何衡量治疗措施的效果呢?答案就是我们今天要介绍的限制性平均生存时间(Restricted Mean Survival
