Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater).
Total sleep duration from type I polysomnography
tst under Sleep Monitoring/Polysomnography/Sleep Architecture in MSP variables
Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep. Conventionally this variable would be called total sleep time (TST)(i.e. total time spent in stage 1 or greater).
Total Sleep Duration: the interval between sleep onset and sleep offset while the participant is asleep from 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
slpprdp under Sleep Monitoring/Polysomnography/Sleep Architecture in CCSHS variables
Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater). Total time from lights out to lights on that is scored as sleep (rounded to nearest minute)
