How to account for covariates with PROC LIFETEST?

[SAS-questioner]

Hi, I want to create a K-M curve with proc lifetest. However, I also have some covariates that needed to be account for because after I put weight variable, it would be the better to account for extra two covariates. Does anyone know how to create a K-M curve with proc lifetest taking two cofounder variables into account? Thank you so much!

You can use the TEST statement to test for the association of covariates with survival time. However, you cannot do a KM analysis or curves that take the covariates into account. See Example 1 in the LIFETEST documentation for a discussion of the TEST statement and it's results.
