Regression: R2 and p value of multiple regression for N9 and N20 produced by median or ulnar nerve stimuli. Group: effect of the group of participants (amyotrophic lateral sclerosis vs controls), coefficient and p value. λ⊥: Effect of the radial diffusivity, coefficient and p value. MD: effect of the mean diffusivity, coefficient and p value. Residuals: coefficient and p value of the constant.

*p<0.05, **p<0.01 and ***p<0.001.
