OR, odds ratio; LL, lower limit; UL, upper limit; ALT, alanine transaminase; AST, aspartate aminotransferase; TC, total cholesterol; TG, triglyceride; BMI, body mass index; CHD, coronary heart disease; BChE, butyrylcholinesterase.
For the multivariate binary logistic regression analysis using a conditional backward method based on the results from univariate binary logistic regression analysis, the values were “/” if variables were excluded before the analysis, and the values were “—” if variables were excluded after the analysis.
