Figure 2. Kaplan-Meier curves of biochemical recurrence-free (BCR-free) survival according to clinical-pathological variables and MT1E expression level.

(A and B) – PCa1 cohort, (C) – PCa1 cohort, only cases with BCR, dichotomized defining early BCR (≤6 mo) as a complete event and late BCR (>6 mo) as a censored event, (D-F) – PCa2 cohort, (G-I) – combined cohort (PCa1 & PCa2). Only parameters significantly associated with BCR or early BCR are shown (p < 0.050).
