Data are presented as n or mean±se. WASO: wake after sleep onset; TST: total sleep time; N1: stage 1 sleep; N2: stage 2 sleep; SWS: slow wave sleep; REM: rapid eye movement; p1: comparison between baseline and CPAP; p2: comparison between baseline and sham-CPAP; p3: comparison between CPAP and sham-CPAP.
