NOTE: Multivariable Cox proportional hazard ratios were computed to determine predictors of biochemical recurrence-free survival. The hazard ratios were computed for a change from the lower quartile to upper quartile in continuous variables. For both surgical margins and seminal vesicle involvement, negative is the reference group.
