Right	1 (0–2)	1 (0–3)	.78
Thalamic injury score (0–3)

Right	1 (1–3)	1 (0–3)	.64
PCWM severity score (0–3)
Left	1 (0–2)	2 (1–3)	.01b
Right	1 (0–2)	2 (0–3	.07
Total injury score (0–18)	8.0 (4–14)	9.5 (4–18)	.38
STN injury (No.) (%)	15 (75)	6 (30)	.01b
Caudate injury (No.) (%)	2 (10)	8 (40)	.06

^aGroups were compared by the Student t-test. All scores and age at onset of seizures are expressed as medians with ranges in parentheses and are compared by the Wilcoxon rank-sum test. The proportion of patients in each group with STN, caudate, and GP injuries was evaluated by the Fisher exact test.

^bStatistically significant, P < .05.
