REM is the period of rapid eye movement sleep, NREM are stages 1, 2, and 3 of sleep, and Total Sleep Time (TST) is the duration of time from "lights out," or bedtime, to the onset of sleep. The amount of actually sleep time in a sleep episode; this time is equal to the total sleep episode less the awake time. TST is the total of all REM and NREM sleep in a sleep episode

Population: REM onset latency is not a standard set of sleep scores analyzed. This is not apart of the analysis, this is in the protocol by error. However the protocol was not amended.

REM Onset Latency (ROL) is defined as the time it takes to get into REM sleep from Sleep Onset.

Population: Data was not analyzed as number of minutes, as minutes is not a meaningful measurement. It is best measured respective to % TST in outcome measure 2. This was included in the protocol in error and the protocol was not amended.

Wake (W), Stages N1,N2,N3 (NREM), and REM (R) sleep. REM is the period of rapid eye movement sleep, NREM are stages 1, 2, and 3 of sleep, and Wake (W) is the duration of time from "lights out," or bedtime, to the onset of sleep.
