  1. Abbreviations: OSA = obstructive sleep apnea; AHI = apnea-hypopnea index; REM = rapid eye movement; NREM = non-REM sleep; AHINREM= apnea-hypopnea index during NREM sleep; AHIREM = apnea-hypopnea index during REM sleep; WASO = wake after sleep onset; MeanSpO2 = nocturnal mean oxygen saturation; MinSpO2 = lowest nocturnal oxygen saturation; ODI = oxygen desaturation index; T90 = percent total sleep duration with below 90% oxygen saturation; T95 = percent total sleep duration with below 95% oxygen saturation; ESS = Epworth sleepiness scale
  2. † Based on the directed acyclic graph, the following covariates were adjusted: age (years), sex (male/female), race (white, black, and other races), smoking status (never/previous/current smoker), and BMI (continuous, kg/m2)
