Table 3 Comparison of demographic, lifestyle characteristics and serum lipid levels between the normal and CAD groups. HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; Apo, Apolipoprotein. ¹Mean ± SD determined by t-test.²Because of not normally distributed, the value of triglyceride was presented as median (interquartile range), the difference between the two groups was determined by the Wilcoxon-Mann-Whitney test
