Table 5. Correlation coefficients between M2-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	Talo-1st metatarsal angle	Calcaneal pitch angle
M2-M5A	r = -0.434 (p < 0.001)	r = -0.204 (p = 0.026)	r = -0.439 (p < 0.001)	r = 0.247 (p = 0.007)
	M1-M2A	M1-M5A	Hardy grade
M2-M5A	r = -0.224 (p = 0.014)	r = 0.689 (p < 0.001)	r = -0.232 (p = 0.011)
