Results were adjusted for age, sex, household income, education level, occupational classification, alcohol consumption, current smoking status, physical activity, obesity, hypertension, and diabetes mellitus. Each sex-stratified analysis was not adjusted for sex. Bold-faced values are statistically significant (p < 0.05).
OR: odds ratio; CI: confidence interval; AMD: age-related macular degeneration.
aLow: Less than 5 hours of sunlight exposure, bHigh: More than 5 hours of sunlight exposure.
