Statistical comparison among b-parameters between regions

DTI Parameter	Comparison	β3	SE (β3)	t	P Value
FA	gCC vs bCC	0.0114	0.0100	1.16	.251
	gCC vs sCC	0.0121	0.0082	1.48	.142
	bCC vs sCC	0.0007	0.0010	0.07	.941
	ALIC vs PLIC	0.0163	0.0042	3.89	<.001
MD	gCC vs bCC	−0.0042	0.0171	−0.25	.805
	gCC vs sCC	−0.0423	0.0173	−2.45	.015
	bCC vs sCC	−0.0381	0.0212	−1.79	.076
	ALIC vs PLIC	−0.0238	0.0084	−2.85	.005

Note:—The gCC and sCC are statistically different for MD. The age-dependent changes in FA and MD are statistically different between the ALIC and PLIC.

β₃ indicates an interaction term; SE, standard error; t, t value; (β₃/SE(β₃); gCC, genu of the CC; bCC, body of the cc; sCC, splenium of the cc.
