Dear all

I use Stata/IC 12.1 for Windows (32-bit). I generated predicted risk of death for each subject in the study by means of Cox proportional hazards model at 8 year of follow-up, a time point at which follow-up was more than 90% complete. It is possible to extrapolate to 10-year the predicted risk of each subjet by assuming an exponential distribution?
Any help would be greatly appreciated.
Thanks for your consideration.
