Univariate hazard ratios (95% CI) for PTEN IHC loss according to Gleason score (<7, =7 and >7), PSA (⩽10, 10–25 and >25 (ng ml⁻¹)), Ki-67 (⩽5% and >5%), extent of disease (<21% and ⩾21%) and risk groups based on the clinical score (score75% quantile). N, D and L denote the number at risk, deaths and PTEN loss counts in each subgroup.
