Values are mean ± SD, with percentage coefficient of variation shown in parentheses. Target refers to regions showing largest group differences in original studies: bilateral thalamus (cLBP) and bilateral precentral gyrus (ALS). Values for blood-based measures (VT and blDVR) exclude plasma outlier subjects.
