I apologize. With STS graph, I used the adjustfor option to create the K-M
plots, to adjust for a covariate, age in this case. When I use stsum to get
the estimate for median survival, the estimate is not adjusted for age.
Visually comparing it to the graph, you can see the difference. I can get
the estimate from the graph, but was wondering if there was a better way to
do this.

What do you mean when you say "adjusted median
survival". Do you mean adjusted for other covariates
or what? Your question is very ambiguous. Please try
to be more specific.
Best,
