Basal ganglia and thalamus volumes comparison. Absolute volumes, relative volumes, and Z scores were compared between ipsi and contralateral sides of the stroke, regardless of the vascular territory, using the Wilcoxon rank sum test. TIV total intracranial volume

Caudate nucleus	4.46 ± 0.87	4.59 ± 0.84	0.14
Putamen	6.08 ± 1.21	6.50 ± 0.90	0.027
Pallidum	1.71 ± 0.34	1.79 ± 0.30	0.15
Thalamus	6.36 ± 1.06	6.67 ± 0.97	0.058
