  1. BMI, body mass index; LDL, low density lipoprotein; HDL, high density lipoprotein.
  2. Values are means ± SD or n (%).
  3. Bivariate statistical analysis using the chi-square test for differences in proportions and two-sided independent t-tests were performed on baseline characteristics using a probability value of 0.05. All between group baseline characteristics were P > 0.05.
