Table 2.

Femoral heads height/length ratios of the two groups

		Treated group n = 12	Control group n = 8
Right femoral head	Mean ± SD	0.50 ± 0.06	0.448 ± 0.09
	Range	0.37–0.65	0.31–0.62
Left femoral head	Mean ± SD	0.51 ± 0.04	0.520 ± 0.07
	Range	0.42–0.57	0.43–0.66
P value (right/left)		0.95	0.16

P value was calculated by comparing the right and left femoral heads using Wilcoxon signed rank test.
