  1. A: patients with preoperative "weak potency" (IIEF score 15 – 18), B and C: patients with preoperative "good potency" (IIEF score 19 – 25).
  2. OIF-RP; Open Intrafascial radical Prostataectomy, IIEF; International Index of Erectile Function.
  3. Note that differences in total numbers of patients are due to some missing data due to incomplete questionnaires.
