Cox Proportional-Hazards (CoxPH) and Kaplan–Meier (KM) survival analyses of relapse-free survival (RFS) using the GENE160, MIR65 and GENE160 + MIR65 signatures in the TCGA-PRAD training dataset. (A) Forest plot visualizing the hazard ratio (HR), 95% confidence intervals and P value of CoxPH survival analysis. (B) KM curves visualizing the survival probabilities over time for high and low risk groups classified based on the median predicted RFS scores in the cohort.
