1 Indicates the significance of the time*group interaction analyzed with the GLM for repeated measures. 2 Indicates the significance of difference within the groups analyzed with the GLM for repeated measures with Bonferroni corrections. 3 Indicates the significance of difference between the groups analyzed with the independent samples t-test with Bonferroni corrections. Letters indicate significance of within-group difference compared to baseline (0 wk) analyzed with paired t-test with Bonferroni corrections. a p = 0.081 b p = 0.024 c p = 0.006 P-values < 0.05 are considered as statistically significant. NS = non-significant |
