Subject: st: Kaplan Meier plot: adding vertical line at median survival
Greetings,
I'd like to plot a Kaplan Meier graph with a vertical line at the point of
median survival, where the line begins at the x-axis and ends at the point
where that vertical line intersects the survival curve.
For example:
sysuse cancer.dta
stset studytime
sts graph, by(drug)
In this example, for drug2 median survival is at 13 months, and for drug3,
at 25 months, so I'd .
Is this possible within the -sts graph- command? I'm using v9.2 and so
don't have the manual graphical editing features of v10.
Thank you.
