Total Sleep Duration (REM): the interval between sleep onset time and lights on/out-bed time while the participant is in REM sleep from type I polysomnography
Total time scored as rapid eye movement sleep (REM), rounded to nearest minute (use calculated variable - sleep wake studies screened out) |

slpprdp |
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). |
