Restricted cubic spline of the relationship between dyslipidemia and sleep latency, REM stage, REM latency, meanSpO2, T95, and time to fall asleep. Potential non-linear relationships were examined using restricted cubic splines (with 3 knots at the 10th, 50th, and 90th percentiles) with odds ratios (ORs) based on logistic regression models. The dashed line represents the OR of 1. ORs were adjusted for age (years), sex (male/female), race (white, black, and other races), smoking status (never/previous/current smoker), and BMI (continuous, kg/m2). Abbreviations: REM = rapid eye movement; MeanSpO2 = nocturnal mean oxygen saturation; T95 = percent total sleep duration with below 95% oxygen saturation
