Odds ratios (95% confidence intervals) were calculated using multivariable logistic regression analysis; Model 1 = not adjusted; Model 2 = adjusted for age, sex, income, education, smoking status, and physical activity; Model 3 = Model 2 + alanine aminotransferase, obesity, hypertension, diabetes mellitus, dyslipidemia, and high-sensitivity C-reactive protein. Q: Quartile.
