Table 6. Correlation coefficients between M1-M5A and loading point/foot deformity parameters.

Data were extracted from Table 3 focusing on intermetatarsal angles and foot deformity parameters. M1-M2A, intermetatarsal angle between first and second metatarsals; M1-M5A, intermetatarsal angle between first and fifth metatarsals; M2-M5A, intermetatarsal angle between second and fifth metatarsals; ADL, activities of daily living; TCA, tibio-calcaneal angle; PFI, pronated foot index; HVA, hallux valgus angle.

	Loading point index	TCA	PFI	Talo-1st metatarsal angle
M1-M5A	r = -0.053 (p = 0.569)	r = 0.100 (p = 0.278)	r = -0.170 (p = 0.064)	r = -0.191 (p = 0.038)
	HVA	M1-M2A	M2-M5A	Hardy grade
M1-M5A	r = 0.560 (p < 0.001)	r = 0.552 (p < 0.001)	r = -0.689 (p < 0.001)	r = 0.331 (p < 0.001)
