Decreased Interhemispheric Functional Connectivity and Its Associations with Clinical Correlates following Traumatic Brain Injury

Table 5

Comparison of fractional anisotropy values in different regions of the corpus callosum between traumatic brain injury patients and healthy controls.

Region	Univariable analysis			Multivariable analysis
	TBI ()	HC ()	-value		-value
Genu	0.52 [0.51, 0.53]	0.55 [0.53, 0.57]	<0.001	0.038	<0.001
Body	0.58 [0.55, 0.59]	0.60 [0.58, 0.63]	<0.001	0.034	<0.001
Splenium	0.68 [0.66, 0.69]	0.70 [0.69, 0.71]	0.002	0.021	0.001

TBI: traumatic brain injury; HC: healthy control. Dependent variable: FA value; Independent variable: group. Adjusted for age, gender, education (years), and total intracranial volume.
