Thank you Alan again! Hope you could also share your thought on my another email about the coding of censoring before death..
Thanks again!

Then the function will calculate CI for each of the 2 types of events >(event of interest and event of competing risk), am I correct? Correct. >What about running regular Cox regression for recurrence? any problem there? for example, need to take into competing risk as well or regular Cox regression is still fine? This is a little trickier. I would strongly suggest reading up on this before doing any analyses. There are a couple of different ways to do this, but the crr function in cmprsk will perform a competing risks regression.
