Sleep Efficiency: the proportion of estimated sleep duration in in-bed period from type III home sleep test
slp_eff under Sleep Monitoring/Polysomnography/Sleep Architecture in BESTAIR variables
Estimated sleep duration, providing an approximation of total sleep duration (i.e. total sleep time) inferred from analysis of non-EEG channels Zhao et al., 2017 (PMID:27707441) 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).
Sleep Efficiency: the ratio of sleep duration (i.e. total sleep time) to in-bed period from type II polysomnography
slp_eff under Sleep Monitoring/Polysomnography/Sleep Architecture in SOF variables
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).Percentage of time in bed that was spent sleeping, or the ratio of total sleep time to total time in bed, expressed as a percentage.
Sleep Efficiency: the ratio of sleep duration (i.e. total sleep time) to in-bed period from type I polysomnography
slp_eff under Sleep Monitoring/Polysomnography/Sleep Architecture in CCSHS variables
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). [100*(total sleep time) / (total time in bed)]
Sleep Maintenance Efficiency: the proportion of total sleep duration (i.e., total sleep time) in sleep period (i.e., interval between sleep onset and offset including wake) from polysomnography

Sleep Maintenance Efficiency: the proportion of sleep duration in sleep period from type I polysomnography
slp_maint_eff under Sleep Monitoring/Polysomnography/Sleep Architecture in CCSHS variables
Sleep duration (i.e., total sleep time, TST) is the interval between sleep onset and sleep offset time while asleep. Sleep period is the interval between sleep onset and sleep offset time.
Sleep Maintenance Efficiency: the proportion of sleep duration in sleep period from type I polysomnography
slp_maint_eff under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables
Sleep duration (i.e., total sleep time, TST) is the interval between sleep onset and sleep offset time while asleep. Sleep period is the interval between sleep onset and sleep offset time.
Sleep Efficiency: the ratio of sleep duration (i.e. total sleep time) to in-bed period from type I polysomnography
slpeffp under Sleep Monitoring/Polysomnography/Sleep Architecture in CFS variables
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).
