| DR | No-DR | Significance | |
|---|---|---|---|
| Age | 13.1 (11 to 16) | 13.8 (12 to 14) | ns |
| Risser’s sign | 1.4 (0 to 3) | 1.8 (0 to 3) | ns |
| Lenke’s type | 25 (type 1); 7 (type 2) | 26 (type 1); 4 (type 2) | ns |
| MT curve preop | 68° (52 to 88) | 64° (50 to 84) | ns |
| Flexibility MT curve | 41 % (22 to 59) | 40 % (15 to 57) | ns |
| MT curve follow-up | 28° (20 to 50) | 35° (25 to 60) | p < 0.05 |
| Final MT curve correction | 61.3 % (39 to 72) | 52.4 % (23 to 66) | p < 0.05 |
| MT curve post surgical loss (final-postoperative) | −1.7° (−4 to 0) | −1.9° (−5 to 0) | ns |
| Fusion levels | 10.3 (8 to 11) | 10.8 (9 to 12) | ns |
