aHC: healthy control.

bMS: multiple sclerosis.

cThis analysis included 18 HCs, 38 people with MS–Normal (ie, with a baseline Nine-Hole Peg Test time below 22.15 seconds), and 29 people with MS-Abnormal (ie, with a baseline Nine-Hole Peg Test time above 22.15 seconds).

dMann-Whitney U test with false discovery rate correction adjusted for age and sex.

eAUC: area under the curve.

fItalic formatting represents a statistically significant P value at <.05.
