  1. -Values expressed as mean ± SD (normally distributed variables) or median and interquartile range (non-normally distributed variables)
  2. ap values indicate comparison between groups by using independent sample t test (normally distributed variables) or Mann-Whitney (non-normally distributed variables) at baseline and ANCOVA test after treatment
  3. bp values indicate comparison within groups by using paired-sample T test (normally distributed variables) or Wilcoxon test (non-normally distributed variables)
