| Day of Measure | Control group (n = 15) | Study group (n = 15) | F-value | P-value |
|---|---|---|---|---|
| Before treatment | 94.20 ± 1.97 | 93.80 ± 1.70 | 0.354 | 0.556 (NS) |
| After treatment | 94.47 ± 1.30 | 94.67 ± 1.40 | 0.084 | 0.775 (NS) |
| Mean difference | 0.27 | 0.87 | ||
| % change | 0.29 ↑↑ | 0.93 ↑↑ | ||
| t-value | −0.385 | −1.483 | ||
