HDL-C: high-density lipoprotein cholesterol. LDL-C: low-density lipoprotein cholesterol. Apo: Apolipoprotein. 1 Mean ± SD determined by the t-test. 2 Because the data were not normally distributed, the value obtained for triglyceride was presented as the median (interquartile range), and the difference between the two groups was determined using the Wilcoxon-Mann-Whitney test.
