*
Automatic estimates significantly different from the referent (IREF and RREF) and independent expert scoring.
AI, arousal index; ALT, alternative scoring; AUT, automatic scoring; EXP, independent expert scoring; IREF, initial referent scoring; REML, latency to rapid eye movement; REMT, time spent in rapid eye movement; RREF, repeated referent scoring; SE, sleep efficiency; SL, sleep latency; SWSL, latency to non-rapid eye movement; SWST, time spent in non-rapid eye movement; TST, total sleep time; WASO, wake time after sleep onset.
