Table 5. Cox proportional hazards regression analysis for prediction of BCR after RP in patients with IRPCa.

CAPRA models		HR (95% CI)	P
CAPRA sum score (continuous)		1.415 (1.185–1.691)	< 0.001
3-group risk model
	Low (CAPRA 0 to 2)	-	-
	Intermediate (CAPRA 3 to 5)	3.950 (1.210–12.891)	0.023
	High (CAPRA 6 to 10)	7.524 (2.291–24.712)	0.001

BCR = biochemical recurrence, RP = radical prostatectomy, IRPCa = intermediate-risk prostate cancer, CAPRA = Cancer of the Prostate Risk Assessment, HR = hazard ratio, CI = confidence interval.
