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). |
