Table 2.
Inter-group and intra-group comparison of the baseline and post-intervention scores (n = 80)
| Group | Baseline scores | Post-intervention scores | t value | P |
|---|---|---|---|---|
| A | 61.2 ± 14.0 | 70 ± 9.1 | 2.89 | 0.008 |
| B | 58.3 ± 10.8 | 87.2 ± 7.8(1) | 7.078 | < 0.001 |
| C | 60.1 ± 14.2 | 86.8 ± 7.1(2) | 6.71 | < 0.001 |
| H/F | 1.647(H) | 8.841 | ||
| P | 0.439 | < 0.001 |
Compared with group A, (1) P<0.001, (2) P = 0.001. (H) indicates that a Kruskal-Wallis test was performed. When comparing post-intervention scores with baseline scores, P<0.05 was considered as statistical significant.
