¹P value is regarded as significant; ^aP value between groups, P value < 0.05 is regarded as significant. Values are mean ± SD. TC: Total cholesterol; LDL-C: Low-density lipoprotein-cholesterol; HDL-C: High-density lipoprotein-cholesterol; SBP: Systolic blood pressure; DBP: Diastolic blood pressure; TG: Triglyceride.
