What does "OS_CNSR" and "PFS_CNSR" mean?

Question

[JACKY]

I've read multiple articles about cancer cohorts. In some of those articles, among the clinical features was "OS_P", "OS_e", "OS_CNSR", "PFS_P_CNSR", and "irPFS_CNSR"..

I know that OS is simply overall survival, and PFS is progression free survival, but what are those extra stuff in the names of those features? What is CNSR and P?

Those "CNSR", "P" and "e" features are binary. So they have nothing to do with time, it seems like they represent an event of some kind, if I'm not mistaken.

Thank you!

From this doc: CNSR variable is created based on the event occurrence and the values are 0 (when the event occurs) and 1 (completed the study without having the event). The corresponding AVAL variable (timing variable in days) is derived.

So in other words, I could say that 1 is still alive, and 0 is dead ?

And what about "PFS_P_CNSR" and "OS_P", what is the meaning of it?
