Table 3 Univariate and multivariate Cox regression analysis of the contribution of potential prognostic factors to biochemical recurrence-free survival of the 77 patients with localized prostate carcinoma who underwent radical prostatectomy

From: Contrast-enhanced transrectal ultrasound can reduce collection of unnecessary biopsies when diagnosing prostate cancer and is predictive of biochemical recurrence following a radical prostatectomy in patients with localized prostate cancer
