Age, weight and prevalence of vertebral deformities by AHD and WOD test results.

		Age (year)	Weight (kg)	Number of subjects with vertebral deformities (%)
		mean ± SD	mean ± SD
AHD1	Positive (n = 63)	72.4 ± 7.6	52.4 ± 8.8	17 (27%)
	Negative (n = 53)	66.8 ± 10.3	52.0 ± 8.0	3 (6%)
	P3	0.001	0.755	0.003
WOD2	Positive (n = 46)	76.8 ± 4.7	52.1 ± 7.2	14 (30%)
	Negative (n = 70)	65.3 ± 8.7	52.3 ± 9.2	6 (9%)
	P3	< 0.001	0.906	0.002

AHD: Arm span-height difference, WOD: Wall-occiput distance

¹AHD positive: ≥ 4.0 cm, AHD negative: < 4.0 cm.

²WOD positive: ≥ 5 mm, WOD negative: < 5 mm.

³P-value by t-test or chi-squared test.
