Total In-bed Period: the interval between lights off/in-bed time and lights on/out-bed time from polysomnography
Conventionally this variable would be called time in bed (TIB). |

Total Sleep Duration: the interval between sleep onset time and lights on/out-bed time while the participant is asleep from type I polysomnography
Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater). |
