Restoration percentage, or gain-to-loss ratio
| Parameter | Total | Gas Group | Nongas Group |
|---|---|---|---|
| Kyphosis angle | 18.9 ± 24.6 | 22.8 ± 26.2 | 12.3 ± 20.3 |
| Wedge angle | 44.1 ± 33.8 | 55.3 ± 29.9 | 31.2 ± 33.8 |
| Height at anterior border | 28.9 ± 31.2 | 40.2 ± 24.1 | 15.9 ± 33.6 |
| Height at center | 26.7 ± 23.7 | 30.6 ± 26.0 | 23.3 ± 21.2 |
Note.—For the kyphosis angle: total, n = 53; gas group, n = 34; nongas group, n = 19. For the other parameters: total, n = 73; gas group, n = 39; nongas group, n = 34.
