  1. Skewed data are presented as the median (interquartile range), normal data are presented as the mean ± standard deviation, and categorical data are presented as the absolute value. Smoking status, drinking status, hypertension, gender and the SNP site were examined by the chi-square test. The serum level of ApoB was examined by the independent samples t test, and the remaining baseline characteristics were examined by the Mann-Whitney test
