Total In-bed Period: the interval between lights off/in-bed time and lights on/out-bed time from polysomnography
tib under Sleep Monitoring/Polysomnography/Sleep Architecture in APOE variables
Conventionally this variable would be called time in bed (TIB).
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).
Total In-bed Period: the interval between lights out/in-bed time and lights off/out-bed time from type I polysomnography

In this study, rest period (i.e. rest interval) is defined as in-bed period (i.e. time in bed).
Standard deviation of the daily midpoint for rest period in main sleep in workdays from actigraphy
sdrestmidpointwo5 under Sleep Monitoring/Actigraphy in MESA variables
In this study, rest period (i.e. rest interval) is defined as in-bed period (i.e. time in bed).
Standard deviation of the daily midpoint for rest period in main sleep in non-workdays from actigraphy

Total number of days with sleep data recorded over all days from actigraphy
sawa47 under Sleep Monitoring/Actigraphy in HCHS variables
This is the number of valid main rest intervals in the recording that meet quality criteria. Main rest intervals are the intervals of time between the epoch at which the participant went to bed and the epoch at which the participant got out of bed, as marked by the scorer. It refers to the participant's nightly time in bed, including time awake and asleep.
Standard deviation of the daily midpoint for rest period in main sleep in all days from actigraphy
sdrestmidpoint5 under Sleep Monitoring/Actigraphy in MESA variables
In this study, rest period (i.e. rest interval) is defined as in-bed period (i.e. time in bed).
