CI = confidence interval; BMI = body mass index; OSA = obstructive sleep apnea
Linear regression models included interaction terms for sleep duration and OSA risk. Adjustments for covariates were made progressively in Models 2–4
Model 2: Adjusted for gender and age
Model 3: Adjusted for variables in Model 2, with additional adjustments for smoking, drinking, physical activity, educational level, and income level
Model 4: Adjusted for variables in Model 3, with additional adjustments for metabolic syndrome, stress level, refractive error, and glaucoma treatment
