Scorer observed unusual sleep staging. This is noted when there is no sleep in any particular stage (eg. no rapid eye movement sleep (REM)).

Data was lost at the end of sleep period because recording ended before wake.

Sleep Heart Health Study Visit 2 (SHHS2)-These vary from 1 (poorest) to 5 (best) and reflect the proportion of sleep time the signals were useable. EEG/EOG/EMG data are defined by the number of hours that sleep stages can be distinguished from awake.
