st: Obtaining median, mean survival with CIs after -stcox- (and/or adjusted -sts graph-)

[graupel75@gmail.com]

Dear statalisters-

Although this terrain has been discussed before, eg

http://www.stata.com/statalist/archive/2009-08/msg01601.html
http://www.stata.com/statalist/archive/2003-01/msg00736.html

there was limited response. I would like obtain the predicted median
and mean survival times, adjusted for covariates, from -stcox- or from
 -sts graph- (which displays adjustment for covariates), but I cannot
access either set of estimates.

While -streg- has -predict median time- and -predict mean time-
options, -stcox- does not, and these estimates don't include 95% CIs.
I cannot think of any inherent methodological reason for this, but
perhaps there is one?

cheers!
