  1. Continuous variables are expressed as mean ± s.d. Categorical variables are expressed as percentages.
  2. CAD, coronary artery disease; BMI, body mass index; LDL, Low-density lipoprotein; HDL, high-density lipoprotein; EH, essential hypertension; DM, diabetes mellitus.
  3. The P value of the continuous variables was calculated by the independent samples t test.
  4. The P value of the categorical variables was calculated by X2 test. *P < 0.05.
