  1. 1 Indicates the significance of the time*group interaction analyzed with the GLM for repeated measures.
  2. 2 Indicates the significance of difference within the groups analyzed with the GLM for repeated measures with Bonferroni corrections.
  3. 3 Indicates the significance of difference between the groups analyzed with the independent samples t-test with Bonferroni corrections.
  4. Letters indicate significance of within-group difference compared to baseline (0 wk) analyzed with paired t-test with Bonferroni corrections.

  6. b p = 0.024
  7. c p = 0.006
  8. P-values < 0.05 are considered as statistically significant.
