Univariate and multivariate logistic regression analyses of the clinical factors.

	Univariate logistic regression		Multivariate logistic regression
Characteristics	OR (95% CI)	P value	OR (95% CI)	P value
ALT (IU/L)	1.012 (1.003–1.021)	0.009∗	1.010 (1.002–1.019)	0.021∗
AST (IU/L)	1.005 (1.000–1.010)	0.066	—	—
GGT (IU/L)	1.002 (1.000–1.004)	0.035∗	1.002 (1.000–1.004)	0.070

Variables with P < 0.05 in the univariate analysis were included in the multivariate logistic regression analysis. ALT: alanine aminotransferase; AST: aspartate aminotransferase; GGT: gamma-glutamyl transferase; OR: odds ratio; CI: confidence interval. ∗ indicates significance with P < 0.05.
