slpeff_d under Sleep Monitoring/Polysomnography/Sleep Architecture in HOMEPAP 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).

Total sleep duration from type I polysomnography and type III home sleep test
tst_modified under Sleep Monitoring/Polysomnography/Sleep Architecture in HOMEPAP variables
Composite total sleep duration based on the diagnostic sleep study and home sleep study. Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep, conventionally called total sleep time. For participants from the type III home sleep test, it is based on estimated sleep duration, which provides an approximation of total sleep duration (i.e. total sleep time) inferred from analysis of non-EEG channels Zhao et al., 2017 (PMID:27707441)This time period is used to calculate indices and other averages.
