  1. Data are expressed as medians (25th percentile, 75th percentiles) or mean ± standard deviation as appropriate. P < 0.05 was considered significant. Value of the difference between the baseline and follow-up serum lipid parameters (TG, TC, HDL-C, and LDL-C). aP values are for between-group differences by Mann-Whitney U test or independent samples t-test. bP values are for within-group differences by Wilcoxon signed-rank test or paired-samples t test
  2. Others: HDL-C high-density lipoprotein cholesterol, HRT hormone replacement therapy, LDL-C Low-density lipoprotein cholesterol, TC total cholesterol, TG triglyceride
