Abbreviation: NAFLD, nonalcoholic fatty liver disease; NHANES, National Health and Nutrition Examination Survey; OR, odds ratio; CI, confidence interval. The multivariate model 1 was adjusted for age, gender, ethnicity, education level, economic status, body mass index, smoking status, alcohol consumption, diabetes, hypertension, total cholesterol, high-density lipoprotein cholesterol, fasting triglycerides, and current use of cocaine, heroin, and/or amphetamine. The multivariate model 2 includes HOMA index in addition to the variables addressed in model 1.
