CCI levels by time of follow-up for men aged 55 or 65 with CCI = 0 at time of diagnosis, who underwent active surveillance, radical prostatectomy, or radiotherapy. CCI levels were modelled with a state transition model. Absolute differences (and 95 % Confidence Intervals) in the proportion of men remaining on CCI = 0 by treatment groups were also estimated (as indicated by the blue arrows)
