Table 1. The correlation relation of the horizontal-center-distance (Horizontal), vertical-center-distance (Vertical), total-center-distances (Distances), and area between the LTA and FTBA (Area).

	Vertical (mm)	Horizontal (mm)	Distances (mm)	Area (mm2)
LTA	9.6 ± 2.9	21.1 ± 5.7	23.4 ± 5.5	22.3 ± 15.4
FTBA	10.4 ± 2.7	20.2 ± 4.8	22.1 ± 4.3	16.6 ± 12.7
r	0.88*	0.82*	0.84*	0.91*

r = Pearson’s coefficient correlation, *p < 0.001.
