Sleep Efficiency: the proportion of estimated sleep duration in in-bed period from type II polysomnography
Sleep Efficiency: the proportion of estimated sleep duration in in-bed period from type II polysomnography

Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep (i.e. total sleep time, TST), while in-bed period is the interval between lights off/in-bed time and lights on/out-bed time (i.e. time in bed, TIB).

Total Sleep Duration: the interval between sleep onset and sleep offset while the participant is asleep from type II polysomnography
Total Sleep Duration: the interval between sleep onset and sleep offset while the participant is asleep from type II polysomnography

Conventionally this variable would be called total sleep time (TST)(i.e. total time spent in stage 1 or greater).
