In clinical research, survival analysis plays a major role, and the choice of visual tool is typically the survival plot. This paper will cover ways to enhance survival plots in SAS. The primary focus will be on the Kaplan-Meier product-limit survival curve for a right-censored survival model. We will discuss the modification of the PROC LIFETEST graph template to customize Kaplan-Meier plots following a well-known approach by Warren Kuhfeld and Ying So. Another approach utilizes a combination of ODS OUTPUT statements for PROC LIFETEST or PROC PHREG, followed by DATA steps to create a dataset that can be graphed via PROC SGPLOT.
