borderline significantp = 0.066
When all patients were included, univariate analysis showed that being in the treatment group RP was the only significant (p < 0.001) predictor of BF while age was borderline significant ( p = 0.066) and multivariate analysis showed that being in the treatment group RP was still the only significant ( p < 0.001) predictor of BF and pretreatment PSA level ≥ 20 ng/mL was borderline significant ( p = 0.069).
