Total Sleep Duration: the interval between sleep onset and sleep offset while the participant is asleep from polysomnography

nsrr_tst_f1 under Harmonized/Polysomnography/Sleep Architecture in MESA variables

Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater).Harmonized by the NSRR team. Source: :slpprdp5:

Sleep Efficiency: the ratio of total sleep duration (i.e., total sleep time) to in-bed period (i.e., time in bed) from polysomnography

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
