Spearmans’ correlation coefficients (r) for pyramidal tract trajectory length (Lt) values with overall (EDSS) and specific (KFS-p) disability scores

EDSSKFS-p
EDSS, expanded disability status scale; KFS-p, Kurtzke functional systems score; Q75, 75th quartile.
Mean Ltr = −0.36, p=0.07r = −0.63, p=0.001
SD Ltr = −0.48, p<0.05r = −0.48, p<0.01
Q75 Ltr = −0.49, p<0.05r = −0.75, p<0.0001
