This paper describes a SAS macro which facilitates the interactive analysis of right-censored survival data. Such data commonly occur in medical studies. The program produces Kaplan-Meier survival curves on a wide variety of graphics devices. The program also performs log-rank and generalized Wilcoxon significance tests among all plotted curves and for each pairwise contrast if desired. Because the program is intelligent and does not prompt the user for information that it can independently obtain, it is quite easy to use.
本文介绍了一个SAS宏，它有助于对右删失生存数据进行交互式分析。这类数据在医学研究中很常见。该程序可在多种图形设备上生成Kaplan-Meier生存曲线。如果需要，该程序还可在所有绘制的曲线之间以及每个成对对比中执行对数秩检验和广义Wilcoxon显著性检验。由于该程序很智能，不会向用户询问它可以独立获取的信息，因此使用起来非常容易。
