Abbreviations: OR, odds ratio; 95% CI, 95% confidence interval. * Conditional logistic regression model, significant at p < 0.05. † Models were stratified by age, sex, income, and region of residence. ‡ Model 1 was adjusted for systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, and hemoglobin level. § Model 2 was adjusted for Model 1 plus obesity, smoking, alcohol consumption, and Charlson Comorbidity Index (CCI) score.
