a Comparison of the T0 measurements between the groups.

b Comparison of the T0 and T1 measurements within the groups. (For a and b; NS: Non significant. *:p ≤ 0.025. **:p ≤ 0.01. ***:p ≤ 0.001).

c Comparison of the T1-T0 changes that were obtained between the groups (For c; NS: Non significant. *:p ≤ 0.05. **:p ≤ 0.01. ***:p ≤ 0.001).
