DOI: 10.1093/sleep/zsac059
Abstract: Abstract Study Objectives Conventional metrics of sleep quantity/depth have serious shortcomings. Odds-Ratio-Product (ORP) is a continuous metric of sleep depth ranging from 0 (very deep sleep) to 2.5 (full-wakefulness). We describe an ORP-based approach that… read more here.

Abstract: STUDY OBJECTIVES The response of sleep depth to CPAP in patients with OSA is unpredictable. The odds-ratio-product (ORP) is a continuous index of sleep depth and wake propensity that distinguishes different sleep depths within sleep… read more here.

DOI: 10.1093/sleep/zsad077.0747
Abstract: The odds ratio product (ORP), a continuous spectral EEG measure of sleep depth, increases in the transition to adolescence and with psychiatric/behavioral disorders; however, its association with cardiac physiology has been largely unexplored. Heart rate… read more here.
