REM Sleep Latency: the interval between the first sleep epoch and REM sleep excluding wake from type I polysomnography
remlaiip under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables
Total sleep time from beginning of sleep to first epoch of rapid eye movement sleep (REM) (excluding wake)
Total Sleep Duration: the interval between sleep onset time and lights on/out-bed time while the participant is asleep from type I polysomnography
