Association of overall ORP with SBP and DBP

% Change in SBP (95% CI)*P value% Change in DBP (95% CI)*P value
Unadjusted model (n=1799)0.7 (−0.1 to 1.4)0.090.2 (−0.5 to 0.8)0.56
Model 1 (n=1765)0.3 (−0.4 to 1.0)0.480.3 (−0.3 to 0.9)0.39
Model 2 (n=1754)0.2 (−0.5 to 1.0)0.510.2 (−0.4 to 0.8)0.51
Model 3 (n=1754)0.3 (−0.5 to 1.0)0.490.2 (−0.4 to 0.9)0.50

  • Model 1: Adjusted for age, sex, race/ethnicity, body mass index (kg/m2), smoking status, cigarette pack-years, alcohol use, periodic limb movement, education level.

  • Model 2: Model 1+hypoxic burden ((%·min)/hour).

  • Model 3: Model 2+duty cycle.

  • *All results reported per SD increment of natural log-transformed ORP.

  • .DBP, diastolic blood pressure; ORP, odds ratio product; SBP, systolic blood pressure.
