nsrr_effsp_f1 Sleep Efficiency: the ratio of total sleep duration (i.e., total sleep time) to in-bed period (i.e., time in bed) from polysomnography

Harmonized by the NSRR team.

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.

nsrr_ttldursp_f1 Total Sleep Duration: the interval between sleep onset and sleep offset while the participant is asleep from polysomnography

Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater).
