Apnea-Hypopnea Index (AHI) normalized (improved) between baseline and follow-up
Indicates an OMAHI3 <= 2 and OAI0P <= 1 at follow-up, whereas one or both of these thresholds were exceeded at baseline. |

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). |
