Hi:
A few things that are worth considering in generating a plot of this type:
(1) I suspect you would want larger point sizes with smaller p-values.

Hello, I have a question about the function lifetab in package KMsurv.
The description of the output value surv says the estimated survival

Are these estimates the ones calculated via Kaplan-Meier probability of
