  1. NPTR Nocturnal penile tumescence and rigidity, TTT total test time, EEE Effective erectile events, TET Total erection time, D60% Duration of erectile episodes with rigidity ≥ 60%, AER Average event rigidity, TST Total sleep time, SOL Sleep onset latency, WASO Wake after sleep onset, REM Rapid eye movement
  2. Group A and Group B were the two groups based on the NPTR results;
  3. N1 and N2 were the first night and the second night for participants’ examination;
  4. Data are presented as mean ± SD;
  5. Differences between Group A and Group B within the first night and the second night were assessed by independent t tests;
  6. * P < 0.05 when measurement on Group A was compared with that on Group B
