ORP, odds ratio product; NREM, non-rapid eye movement sleep; TRT, total recording time; ORP-9, ORP in first 9 s after end of arousal; CSI, cumulative sleep index; OSA, obstructive sleep apnea; SSD, short sleep duration; ESS, Epworth sleepiness scale; SF36(P), standardized score of SF-36 physical component Scale; SF36(M), standardized score of SF-36 mental component Scale; Descriptors below the values refer to where the range is relative to the total range for the indicated variable. For ORPWAKE, low values indicate drowsy wakefulness, while low values for ORPNREM, ORPTRT and ORP-9 indicate deep sleep, and faster sleep recovery after arousals; and vice versa.
