I have large database of hundreds of thousands observations. When I used spss to analyze KM survival, it gave me mean and median survivals with 95 % confidence interval. However, I need 1-, 3- and 5- year survival too. It's difficult to figure out using the curves. I am missing something? I also tried life tables, but I am not sure about it's accuracy? Can anyone please throw light here.
Thank you.?
