Table 2. This table shows mean and standard deviation, and median with Friedman test results. Statistically significant differences between the study times in group A and group B were founded according to Friedman test P<0.05. Post hoc pairwise comparisons for T1/T2 and T0/T2 showed there were statistically significant differences according to Wilcoxon signed rank test with Bonferroni corrections in both groups when P<0.0167.
