st: survival curve for a stratified analysis using matched data

[<kelynch@bidmc.harvard.edu>]

Hi,

I am working on a survival analysis using a 1:2 variably matched dataset.  A reviewer is asking for a survival curve to accompany the proportional hazards model I've used and Stata is not allowing me to use the "stcurve, survival" command on a stratified model.  I need to keep the model stratified on matched group to account for the matched pairs.

My code:
xi: stcox i.rx_tzd, str(group) vce(robust)
stcurve, survival at1(_Irx_tzd_1=1)  at2(_Irx_tzd_1=0)
** error message from Stata:   "stcurve not allowed after stcox, strata()"

Is there any way to create a survival curve from a stratified analysis in Stata?
I am using Stata/SE version 12.1.

Thanks for your help,

Katie Lynch
