Mean (SD). 1 Indicates the significance of difference between the groups analyzed with the Mann-Whitney test with Bonferroni corrections. 2 Indicates the significance of difference within the group analyzed with the Wilcoxon test with Bonferroni corrections. 3 Indicates the significance of difference between the groups analyzed with the independent samples t-test. 4 Indicates the significance of the time*group interaction analyzed with the GLM for repeated measures. 5 Indicates the significance of difference between the groups analyzed with the independent samples t-test with Bonferroni corrections. 6 Indicates the significance of difference within the group analyzed with the paired samples t-test with Bonferroni corrections. 7 Indicates the significance of difference between the groups analyzed with the Mann-Whitney test. 8 Indicates the significance of difference between the groups analyzed with the GLM for repeated measures. 9 Indicates the significance of difference within the groups analyzed with the GLM for repeated measures. P-values < 0.05 are considered as significant. NS = non-significant |
