Hazard Ratio (HR) >1 (<1) indicates higher (lower) risk for the second group. GSTP1, % GSTP1 methylation; CF, clinical failure; CI, confidence interval; HM, high methylation; LM, low methylation; MM, moderate methylation; PCa1 and 2, cohorts 1 (n = 147) and 2 (n = 71) of patients with high-risk prostate cancer; PCa1+2, a combined group of patients from PCa1 and PCa2.
