Your question is not clear. There cannot be two KM curves that both are
based on the same individuals, as the KM curve is unique, given the
sample. As asked in the FAQ Section 3.3, please show us the Stata
commands that produce the KM curves that you wish to compare. If you
can, illustrate the problem in one the data sets referenced in the
-help- for the command.

I want to compare the predictive value of two different variables in the same dataset. Note that the all individuals are in both K-M curves.
Thanks,
