^aAnalysis of variance was used to analyze between-group differences in continuous variables. For categorical variables, Fisher’s exact test or chi square test was used. BMI, body mass index; HDL, high density lipoprotein; LDL, low density lipoprotein; SBP, systolic blood pressure; DBP, diastolic blood pressure.
