Paired Student's t-test or ∗Wilcoxon matched pairs test, significant results, P < .05; data are expressed as mean ± SD. TST: total sleep time; SE: sleep efficiency; SOL: sleep onset latency; REM: rapid eye movements; LREM: REM sleep latency; TWT: total wake time; WASO: wake time after sleep onset; AHI: apnea hypopnea index; PLM: periodic leg movements.
