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

	PSI recovery slope	EF recovery slope	VL recovery slope
CBF: Meta-ROI	0.43 (p = 0.015)	0.33 (p = 0.06)	0.28 (p = 0.13)
Jacobian: Ventricles	–0.23 (p = 0.23)	–0.07 (p = 0.7)	–0.24 (p = 0.21)
Jacobian: Meta-ROI	0.19 (p = 0.31)	–0.12 (p = 0.52)	0.07 (p = 0.72)

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.
