| β | SE | Wald x2 value | P value | OR | 95% CI | |
|---|---|---|---|---|---|---|
| Model 1 | 0.586 | 0.152 | 14.935 | <0.001 | 1.796 | 1.335–2.418 |
| Model 2 | 0.674 | 0.155 | 18.956 | <0.001 | 1.963 | 1.449–2.659 |
| Model 3 | 0.587 | 0.157 | 14.07 | <0.001 | 1.799 | 1.324–2.445 |
| Model 4 | 0.458 | 0.188 | 8.454 | <0.005 | 1.580 | 1.161–2.152 |
Note: Model 1 was unadjusted. Model 2 was adjusted for age and sex. Model 3 was adjusted for age, sex and body mass index. Model 4 was adjusted for all Model 3 variables associated plus these associated with metabolic syndrome, including waist circumference, systolic blood pressure, diastolic blood pressure, triglycerides, HDL cholesterol, and fasting blood sugar. β is partial regression coefficient; SE is standard error of partial regression coefficient; OR is odds ratio; CI is confidence interval. P-value specifies the possibility that a parameter is not a risk factor for NAFLD.
