Extrapolating Cox predicted risk

1 message · Prof. Mario Petretta

Dear all

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.
