Kaplan-Meier估算,就是在患者中途失联的情况下估算生存率的最简单方法。 The Kaplan-Meier estimate is the simplest way of computing the survival over time in spite of all these difficulties associated with subjects or situations. 前提假设: 生存前景一致假设。假设中间失去联系的患者未来生存状况与剩下的患者...
Kaplan-Meier法 Kaplan-Meier法简称K-M法,又称乘积极限法(Product-limit Estimate)是生存分析方法中最常用的一种,主要用于估计患者生存率和绘制生存曲线。 Kaplan-Meier曲线(生存曲线)以生存时间为横轴,生存率S (tk)为纵轴,绘制而成的连续型的阶梯形曲线,用以说明生存时间与生存率之间的关系。 生存曲线一般是平滑...
Kaplan-Meier estimate (kap'lăn mī'ĕr), nonparametric method of compiling life tables or survival tables that combines calculated probabilities of survival with estimates to allow for censored (missing) observations; used mainly in survival studies of cancer and similar long-term diseases. ...
