  1. A: patients with preoperative weak potency (IIEF score 15 – 18); B: patients with preoperative good potency (IIEF score 19 – 25).
  2. OIF-RP; Open Intrafascial radical Prostatectomy, BMI; Body Mass Index, IIEF; International Index of Erectile Function, intraop.; intraoperative.
  3. Note the change of the total patients’ number due to some missing data or incomplete questionnaires.
