Data are presented as mean±se. WASO: wake time after sleep onset; TWT: total wake time; TST: total sleep time; N1: stage 1 nonrapid eye movement (NREM) sleep; N2: stage 2 NREM sleep; SWS: slow wave sleep; REM: rapid eye movement; AHI: apnoea/hypopnoea index; S_a,O₂: arterial oxygen stauration. *: p<0.05 between baseline and post-CPAP treatment; ^#: p<0.05 between CPAP and sham-CPAP.
