TABLE 1.
Comparison of the differences in visual analogue scale (VAS) and pinprick test (PP) scores among the three group (M(P25, P75)).
| Control group (n = 11) | CGF group (n = 10) | Laser group (n = 10) | Sum (n = 31) | H | p | ||
|---|---|---|---|---|---|---|---|
| VAS change | Day 8 | 1 (0, 1) | 1 (0, 2.25) | 1.5 (0, 2) | 1 (0, 2) | 1.227 | 0.541 |
| Day 14 | 2 (1, 2) | 3 (2.75, 4.25)a | 4 (4, 5)b | 3 (2, 4) | 15.414 | <0.001* | |
| Day 20 | 2 (2, 2) | 3 (3, 6)a | 5 (4, 6)b | 3 (2, 5) | 16.903 | <0.001* | |
| Day 30 | 2 (2, 3) | 5 (3, 6)a | 5 (4.75, 6.25)b | 4 (3, 5) | 15.396 | <0.001* | |
| PP change | Day 8 | 1 (0, 2) | 2.5 (0.75, 3) | 2 (1, 3.25) | 2 (1, 3) | 4.717 | 0.095 |
| Day 14 | 2 (1, 3) | 5 (3.75, 5)a | 6 (4, 7)b | 4 (2, 5) | 18.318 | <0.001* | |
| Day 20 | 3 (2, 3) | 5 (4, 5.25)a | 7 (5.75, 8)b | 5 (3, 6) | 22.340 | <0.001* | |
| Day 30 | 3 (2, 4) | 5.5 (5, 7)a | 8 (6.75, 9)b | 5 (4, 7) | 23.660 | <0.001* |
Note: * indicates p ≤ 0.05, suggesting a statistical difference. a represents the CGF group, and the control group has a statistical difference. b represents the laser group, and the control group has the statistical difference. The VAS change is the baseline value minus the time point values. The PP change value is the value at each time point minus the baseline value.
