Cobb angle (angular value) of the scoliosis curve

Cobb angle	Beginning (T0)	In brace (T1)	End of treatment (T2)	Final F.U. (T3)
Average A.V.	27° ± 6.7°	7.6° ± 7.4° (72 % of correction) (t = 19.8; p < 0.0001)	8.5° ± 8.6° (69 % of correction) (t = −13.7; p < 0.00001)	11.0° ± 7.4° (59.3 % of correction) (t = −13.9; p < 0.0001)
A.V. before menarche (34)	28.5° ± 7.1°	7.4° ± 8.6° (t = 17.6; p < 0.0001)	7.8° ± 9.5° (t = 13.5; p < 0.0001)	10.9° ± 7.8 (t = 13.6; p < 0.0001)
A. V. after menarche (14)	23.7° ± 3.9°	8.3° ± 3.5° (t = 13.2; p < 0.0001)	10.1° ± 6.1° (t = 6.4; p < 0.0001)	11.2° ± 6.7 (t = 5.7; p < 0.0001)
T	2.34	−0.37	−0.85	−0.11
p	0.01	>0.05	>0.05	>0.05

In the multiple regression logistic model there is no correlation between the angular Cobb value at final follow-up and menarche
