Hi,
I have plotted two separate Cox survival curves (corresponding to two Cox
models). How do I overlay the two plots (containing 2 curves, because
stcurve, by variable command used) into one single graph)? I tried graph
combine (not what I want) and addplot (does not seem to work).
Hope you can assist with this.
Thanks
Regards,
Agnes
