Result of Correlation Analysis between Neuropsychological Tests and ROI-Based Measures of CBF and Structural Atrophy among the TBI Group

	PSI	EF	VL
CBF: Meta-ROI	0.24 (p = 0.16)	0.43 (p = 0.01)	0.20 (p = 0.24)
Jacobian: Ventricles	–0.56 (p = 0.001)	–0.48 (p = 0.004)	–0.11 (p = 0.55)
Jacobian: Meta-ROI	0.21 (p = 0.23)	0.26 (p = 0.13)	–0.08 (p = 0.64)

Bolded values indicate statistical significance.

ROI, region of interest; CBF, cerebral blood flow; TBI, traumatic brain injury; PSI, Processing Speed Index; EF, Executive Function Composite; VL, Rey Auditory Verbal Learning Test.
