Data for fasting plasma glucose, triglycerides, aspartate transaminase, and γ-glutamyl transpeptidase were skewed and were log-transformed for analysis. Bolded numbers indicate significance
β standard coefficient, R² coefficient of determination
§Multivariate adjusted for all confounding factors in Table 1 by multiple linear regression analysis using backward elimination method. Only factors remained in the final model were shown
