Sleep efficiency is the proportion of sleep duration (i.e. total sleep time, tst) in total rest period (i.e. rest interval) in main sleep. Sleep duration is the interval between sleep onset time and sleep offset time while asleep. In this study, rest interval is the same as in-bed period.

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)]

Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater). Total time from lights out to lights on that is scored as sleep (rounded to nearest minute)
