Biochemical Failure Free Progression at 10 Years. Comparing predicted (Model FP) versus observed survival (Kaplan-Meier Survival), in 321 men treated by radical prostatectomy. Model FP, indicates flexible parametric survival final model on scale hazard, incorporates the presence of CPC and mM, with four degrees of freedom for baseline hazard function (DF4) and CPC as variable time-dependent effect (TVC) with one degrees of freedom (DFTVC1). The Kaplan- Meier Survival was 100% before of 2.17, 2.58, 0.42 and 0.83 years respectively for groups A, B, C and D.
