Dear Statalisters,

I have constructed a Kaplan-Meier graph created with --sts graph--. Everything is great with it except I would like to add a 95% CI at one or two points along the two curves, which are plotted by group (it is a RCT).

I have added the option "ci" which plots 95% CI bands, but what I would prefer would be a 95% CI bar at one or two points without bands.

I have investigated 'ciopts' to no avail.

Any ideas how this could be done?

Many thanks,

Phil
