Sleep Efficiency: the proportion of total sleep duration in in-bed period from type II polysomnography
Sleep Efficiency: the proportion of total 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, while in-bed period is the interval between lights off/in-bed time and lights on/out-bed time. Conventionally, this variable could be described as the ratio between total sleep time (TST) and time in bed (TIB).
