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 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 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 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 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.
