Need Help: Kaplan Meier analysis

Postby survivinganalysis » Sat Nov 28, 2015 5:12 am


I have a large database and have generated KP curves for long term survival but there is no difference in overall/long term survival. Our goal is to evaluate if there is a difference in one year survival and looking at the curve, it looks like there is difference at 1-yr interval. I was wondering, how do I calculate the one year survival only along with CIs. Thanks. (using SPSS)
