Table 3. Analysis of variance, F test and p-value of measures Y1, Y2, Y3 and Y4 obtained in both study groups.

Measures	F test	P value	Variance
Y1	237.08	< 0.0001	20.5
Y2	0.13	0.72	19.5
Y3*	2648.21	< 0.0001	7.1
Y4	147.45	< 0.0001	25.7

Y1: U width/tibia; Y2: U height/tibia); Y3: area; Y4: U width/U height.

* Variables transformed into logarithms, aimed at homogenizing the variances.
