Table 2.

Rotation of apical vertebra (angular value in Perdriolle degrees)

A.V.	Beginning (T0)	In brace (T1)	End of treatment (T2)	Final F.U. (T3)
Average rotation	9.3 ± 4.8	2.2 ± 3.8 (t = 10.6; p < 0.0001)	3.2 ± 3.7 (t = 8.7; p < 0.0001)	4.1 ± 3.9 (t = 8.4; p < 0.0001)
Before menarche (34)	9.5 ± 4.5	2.1 ± 3.9	3.1 ± 3.7	3.9 ± 3.6
After menarche (14)	8.9 ± 5.7	2.6 ± 3.4	3.7 ± 4.0	4.4 ± 4.6
T	0.35	−0.37	−0.54	−0.36
p	>0.05	>0.05	>0.05	>0.05

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