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.

DOI: 10.1093/sleep/zsac321
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.

DOI: 10.1093/sleep/zsae067.0095
Abstract: Prior data shows an association between the odds ratio product (ORP), a continuous EEG measure of sleep depth, with heart rate variability (HRV), a continuous EKG measure of cardiac autonomic modulation. Nutritional lifestyle choices can… read more here.

DOI: 10.1093/sleep/zsae067.0583
Abstract: In split studies in academic sleep centers, CPAP improved NREM sleep depth, measured by the Odds-Ratio-Product (ORP, range 0 (deep sleep) to 2.5 (full-wakefulness), in only three (of 9) ORP types characterized by having <… read more here.

DOI: 10.1111/jsr.70074
Abstract: Conventional sleep staging categorises sleep into discrete stages, which may not capture the continuous nature of sleep depth. We aimed to develop a data-driven continuous measure of sleep depth-ordinal sleep depth (OSD)-using a deep learning… read more here.
