Total Sleep Duration: the interval between sleep onset and sleep offset while the participant is asleep from polysomnography
Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater). |

Apnea-Propensity Index to be excluded for being above threshold - potential artifact
The Apnea Propensity Index (API) is a novel measure of breathing variability based on the abdominal effort channel and optimized around the first sleep onset. |

PSG Quality Assessment: Apnea/Hypopnea scoring problems
Due to signal problems, scorer was unable to reliably distinguish between apnea and hypopnea events. The distinction between apnea and hypopnea was determined to be unreliable. |

PSG Quality Assessment: Arousals unreliable
Due to signal problems, scorer was unable to reliably assess arousals. The scoring of arousals was determined to be unreliable. |

PSG Quality Assessment: Arousals unreliable (REM)
Due to signal problems, scorer was unable to reliably assess arousals in stage REM. The scoring of arousals in stage REM was determined to be unreliable. |
