Total Sleep Duration: the interval between sleep onset time and lights on/out-bed time while the participant is asleep from type I polysomnography
slpprdp under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables
Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater).
Total Sleep Duration (REM): the interval between sleep onset time and lights on/out-bed time while the participant is in REM sleep from type I polysomnography
timerem under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables
Total time scored as rapid eye movement sleep (REM)
Sleep Latency: the interval between lights-out/in-bed time and sleep onset from polysomnography

Percentage of total sleep duration in non-supine position from type II polysomnography
nsupinep5 under Sleep Monitoring/Polysomnography/Sleep Architecture in MESA variables
Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep, conventionally called total sleep time.
Sleep Latency: the interval between lights-out/in-bed time and sleep onset time from type II polysomnography

Total Sleep Duration: the interval between sleep onset time and lights on/out-bed time while the participant is asleep from type I polysomnography
tst under Sleep Monitoring/Polysomnography/Sleep Architecture in APOE variables
Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater).
