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.<BR /> Wed, 18 May 2022 11:19:24 GMT OsoGris 2022-05-18T11:19:24Z https://communities.sas.com/t5/Statistical-Procedures/How-to-account-for-covariates-with-PROC-LIFETEST/m-p/813965#M40160 <P>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!</P> Tue, 17 May 2022 23:07:06 GMT https://communities.sas.com/t5/Statistical-Procedures/How-to-account-for-covariates-with-PROC-LIFETEST/m-p/813965#M40160 SAS-questioner 2022-05-17T23:07:06Z https://communities.sas.com/t5/Statistical-Procedures/How-to-account-for-covariates-with-PROC-LIFETEST/m-p/814034#M40161 You can use the TEST statement to test for the association of covariates with survival time.
