Correlation between longitudinal changes in corticospinal tract diffusion measures and changes in ALS Functional Rating Scale (mixed model²⁹)

	Correlation	P value
Right Corticospinal Tract FA	0.4526	0.0078
Left Corticospinal Tract FA	0.6554	0.0031
Right Corticospinal Tract MD	−0.5965	0.0061
Left Corticospinal Tract MD	−0.6347	0.0079

FA – fractional anisotropy; MD – mean diffusivity
