Data are presented as odds ratios (OR) and 95% confidence intervals (CI) using multiple logistic regression analysis.

Multiple logistic regression model was additionally adjusted with age, sex, tooth brushing frequency, alcohol intake and tobacco smoking in Model 1; BMI was further adjusted in Model 2.

LDL-C low density lipoprotein cholesterol, HDL-C high density lipoprotein cholesterol.
