(A) Hazard ratio (HR) with 95% confidence interval for recurrence by degree of nerve-sparing for all patients and patients with negative versus positive surgical margins, adjusted patient age, preoperative prostate-specific antigen, International Society of Urological Pathology grade in surgical specimen, pathological stage, prostate weight and surgeon prior experience and annual volume. (B) HR with 95% confidence interval for recurrence according to pathological stage with versus without positive margins, adjusted for patient age, preoperative prostate-specific antigen, International Society of Urological Pathology grade in surgical specimen, prostate weight, and surgeon prior experience and annual volume. (C) Odds ratio (OR) with 95% confidence interval for positive surgical margins for different degrees of nerve-sparing according to pathological stage, adjusted for patient age, preoperative prostate-specific antigen, International Society of Urological Pathology grade in surgical specimen, prostate weight, and surgeon prior experience and annual volume.

Intra = intrafascial nerve-sparing surgery; Inter = interfascial nerve-sparing surgery; None = no nerve-sparing; Semi = semi–nerve-sparing surgery.
