* Conditional logistic regression analysis, significance at P < 0.05

† Conditional model including age, sex, income, region of residence, hypertension, diabetes, and dyslipidemia history

‡ Model adjusted for obesity, smoking status (current or past smoker vs. nonsmoker), and frequency of alcohol consumption (≥ 1 time per week compared to < 1 time per week)
