Patients with no history of urethral dilatation before treatment had a better 5-year actuarial success rate, that was almost significant ( Fig. 2 c, P = 0.058).
Patients with no history of urethral dilatation before treatment had a better 5-year actuarial success rate, that was almost significant ( Fig. 2 c, P = 0.058).
To study the independent effect of prognostic factors on estimates of success rate, only at least borderline significant variables were entered into a multivariable analysis with a Cox proportional-hazards model.
