What I'm trying to do is to plot survival curve for 2 different groups: slope_95gp=0 and slope_95gp=1.
Of course, at the same time, I need to adjust for confounding effect: sex age bmi_1 smoke alcohol ldl_c meansbp nightdaysbpratio
Though I've succeded creating the graph I want for this 2 groups using PROC PHREG (see plots1&2 in the attachment), I can't make it draw on the same plot.
I've checked some documents, and it suggest me using plot statement -- overlay (SAS code see Demo in the attachment). However, it didn't work.
Therefore, I come here to ask for help.
Thank you in advance!
