A Method to Generate Kaplan-Meier and adjusted survival curves using SASB harat Thakkar, Kwan Hur, William G. Henderson, and Charles Oprian Department of Veteran affairs cooperative Studies Program Hines, ILAbstract Kaplan-Meier (K-M) survival curves can begenerated using SAS PROC LIFETEST. In thepresence of significant covariates, adjusting thesurvival curves is necessary. In this paper a step bystep Method is presented to produce survival curvesthat adjusted for the covariates. This is accomplishedusing SAS PROC PHREG and SAS PROC In clinical research often a comparison ofsurvival curves is made between treatment SAS PROC LIFETEST produces K-M survivalcurves that depend only on time. However, thesurvival curves may depend on both time andcovariates. Here, adjusting the survival curves forthese covariates is problem faced is to devise a Method ofgenerating survival curves adjusted for thecovariates.
