Sleep Study: hours of sleep
A subset of participants had home sleep test (Edentec) as well as in-lab polysomnography at visit 5. |

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). |
