How to overlay 2 survival plots with adjustment of confounders

[Chung-Li]

Hi all, 

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!

It may be possible to help if you include the data set so I can run your program.

Which release of SAS are you using?
