  1. Notes:
  2. OR Odds Ratio, CI Confidence interval, df Degree of freedom, REF Reference group
  3. The model reasonably fits well (Hosmer-Lemeshow test: p = 0.168)
  4. Model assumptions were met
  5. No significant interactions and multicollinearity problem
  6. Model explained between 23.1% (Cox and Snell R Square) and 30.8% (Nagelkerke R Square) of the variance in NAFLD group and correctly classified 73.4% of cases
