Subject:      Restricted mean survival time in PHREG?

I've used the LIFETEST procedure to produce a restricted mean survival time
- the average survival time over an interval.   I've reviewed the PHREG
documentation but can't find evidence of a correspondingly simple way to
produce a restricted mean survival time when the survival analysis is
adjusted for the values of other covariates, as one might do in the PHREG
procedure.  Is there such a capability?



I'd use the median survival time, but the rate of attrition is sufficiently
low as to make the median undefined in all but one of the groups.



Thanks,
