disease-free survival(DFS,无病生存期):指从开始到肿瘤复发或者任何原因死亡的时间;常用于根治性手术治疗或放疗后的辅助治疗,如乳腺癌术后内分泌疗法等: event free survival(EFS,无事件生存期):指从开始到发生任何事件的时间,这里的事件包括肿瘤进展,死亡,治疗方案的改变,致死副作用等(主要用于病程较长的恶性肿瘤...
- The Cox proportional-hazards model (Cox, 1972) Cox比例风险模型是常用与医学研究中的回归模型,通常用于研究预测变量与生存时间的关系 - Kaplan-Meier curves 与 logrank test tests属于单因素分析的例子,他们研究的是单一变量与生存的关系,并且Kaplan-Meier与log-rank检验只适用于分类变量,却并不适用于数值型变...

Kaplan–Meier Curves E.L. Kaplan and P. Meier developed this form of survival graph in connection with a non-parametric estimate of the survival function at each death or censoring time. For small samples, this Kaplan–Meier product limit method provides a more accurate representation of the su...
Objectives Kaplan-Meier (KM) curves are commonly used to report time-to-event outcomes like overall survival (OS) and progression-free survival. For studies not explicitly reporting hazard ratio (HR) and confidence intervals (CI), KM cur... J Gupta,MK Bhutani,R Kumar,... - 《Value in ...
3-B patients are still alive at last follow up after 37,69 and 213 weeks. I am then asked to construct the survival curves for both groups and use logrank test to test whether there is a significant (alpha=0.05) difference in survival between the two groups. ...
Kaplan-Meier curves and estimates of survival are the most common way to present survival data in medicine, especially for cohorts with different lengths of follow-up. Moreover, Kaplan-Meier curves present a frequently used general graphic approach to display time-to-event outcomes. A solid unders...
In addition, you should decide whether the survival curves are similarly shaped, even if they are above or below one another. This has implications for the choice of statistical test that is used to analyse the results from the Kaplan-Meier method (i.e., whether you use the log rank test...
Kaplan Meier Survival Analysis using Prism 3 With some experiments, the outcome is a survival time, and you want to compare the survival of two or more groups. Survival curves show, for each plotted time on the X axis, the portion of all individuals surviving as of that time. The term ...
