I have not heard anybody discuss how the individual patient would compare to the ITT population of the wonder drug's P3 where it established 80% OS.
This goes to 2 issues, one is tags "real world" odds of being positive. Another is that negatives might well have some related condition that is affecting survival.
I kind of suspect though that entire point of this has nothing to do with the answer, but that fact that one has to keep digging past the surface. Both in Clarks's puzzle and real world biotech results.
