I have the same question. I want show #in-risk(#censored) at each time interval below KM plot. #censored is #patients who did not have event but lost follow up prior the time point (Censored at last contact), they are hash markers in survival curve.   Thanks!       ... View more

It is time to event outcome. We usually report probability of survival at a particular time (Such as progression-free survival at 3 years, x% for group A and y% for group B), but an journal reviewer requests us to report survival difference and 95% of the difference  at a time point.

In general, patients don't change cetert in a multicenter follow up study, we can set 'random intercept / subject=center; random intercept /subject=patient(ceter)' to account center variability. What if some patients changed center in middle of follow up (a patient had test in center1 in visit 1 and 2 then mobed to center2  for visit 3 and 4)?   proc glimmix; class patient center; model outcome=visit; random intercept / subject=center; random intercept /subject=patient(center); run;   Thanks, HL       ...
