DIRADJ option in Proc Phreg

[CHELS]

Hello experts,

I read that there are 2 methods for adjusting survival curves: 1) average covariate method and 2) corrected group prognosis method. 

Will Proc Phreg with "baseline covariates" and "DIRADJ" option output result using corrected group prognosis method? If so can numeric variables be incorporated? 

Thank you!
