  1. Data are reported as mean ± standard deviation or as number (percentages). P-value reported as the result of aAnalysis of variance (ANOVA) and bChi-square. Statistically significant P-values are bolded(P-value < 0.05).
  2. BMI = body mass index, BP = blood pressure, HDL = high density lipoprotein.
