  1. The data are expressed as the mean ± SD
  2. No significant differences in any variable were observed between the two groups at baseline, as determined using unpaired Student’s t-test
  3. a Calculated as (value at week 24 – value at baseline)/value at baseline × 100
  4. b The effects of the intervention on these variables were evaluated by repeated-measures ANOVA
  5. c P < 0.05 vs. baseline, as assessed by paired Student’s t-test
  6. d P < 0.05 vs. percentage changes in the placebo group, as assessed by unpaired Student’s t-test
