You could tinker with something like this:
sysuse cancer.dta, clear
stset studytime
drop if drug==3
sts test drug
local chi_res logrank P = `=round(r(chi2), .01)'
sts graph, by(drug) risktable text(.05 5 "`chi_res'", place(ne) size(small)
col(red))

Subject: sts test: displaying log-rank test of equality within a Kaplan
Meier graph
Dear Statalist members,
I'm creating a Kaplan-Meier graph, and also performing the log-rank
test of equality, for example:
sysuse cancer.dta, clear
stset studytime
drop if drug==3
sts graph, by(drug) risktable
sts test drug
My question: is it possible to display the results of the log-rank
test in a small window within the area of the Kaplan-Meier survival
curve?
Best wishes,
Michael McCulloch
