National Institutes of Health Stroke Scale (NIHSS), LE MI (lower extremity motricity index), UE MI (upper extremity motricity index), Mississippi Aphasia Screening Test (MAST), Functional Independence Measure (FIM) and Symbol Digits Modality Test (SDMT). Each sphere is located at the center of the gray matter region it represents. Sphere size is proportional to the relative impact of that region's ChaCo score on the outcome measure. Blue spheres indicate regions whose ChaCo scores significantly increase the value of the predicted outcome (positive coefficients), while red spheres indicate regions that significantly decrease the value of the predicted outcome (negative coefficients). Black spheres indicate regions of non-significant influence.
