How to calculate the percentage of death-censored event-free survival ?

[Suwasin Udomkarnjananun]

Hello, I have problem with calculating 10-year event-free survival percentage.

When I plotted the KM curve, the 10-year event-free survival rate seemed to be around 0.60.

But when I use stdescribe, the mean of failure events was 0.26. Thus made event-free survival rate around 0.74, which was much higher than observed from the KM curve.

I suspect this was due to some of patients were censored from dead, but I don't know how to calculate the exact value of the death-censored 10-year event-free survival.

Thank you for your help

So, the first thing is to make sure you have correctly -stset- your data. As you do not show your code, nor any example data, it is not possible to tell. But if the -stset- command is wrong, nothing thereafter will be correct.

Once your data is -stset-, the easiest way to get the survival probability at any given time is with -sts list-. See -help sts list-.

Thank you very much.

the -help sts list- is exactly the one I look for
