  1. The bold numbers, P value was < 0.05, and the difference was statistically significant
  2. HDL-C, high density lipoprotein-cholesterol; TG, triglycerides;Low means < 50% concentration; High means ≥ 50% concentration; Low Cu + Low Zn, Low Cu + Low Mg and Low Zn + Low Mg were taken as the reference; Shown are the odds ratios (ORs) and 95% confidence intervals.; -, the results didn’t have statisticlly significance
