OR = odds ratio; aOR = adjusted odds ratio; CI = confidence interval

Logistic regression was used to estimate ORs and 95% CIs. Adjustments followed the same model progression as that in Table 2

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 intraocular pressure, metabolic syndrome, stress level, and refractive error
