| N. | % | N. | % | N. | % | N. | % | N. | % | N. | % | |
| ITT analysis | 82 | 100 | 64 | 78.0 | 18 | 22.0 | 50 | 61.0 | 23 | 28.0 | 9 | 11.0 |

The primary outcome was defined as “success” when main curve was below 50° upon reaching skeletal maturity, and “failure” otherwise. The secondary outcome was classified as follow: 1) improved – reduction of main curve >5°; 2) unchanged – change of main curve ≤5°; 3) progressed – increase of main curve >5°. PP: per protocol; ITT: intention to treat.
