Significant results from regressions examining MD as a function of age across six ROIs of the corpus callosum for PKU and control groups

ROI	Age			Group			Age × group
	R ²	F	P	Δ R ²	Δ F	P	Δ R ²	Δ F	P
Genu	0.13	13.67	0.001	0.26	39.93	0.001	0.04	7.13	0.009
Rostral body	0.07	6.50	0.02	0.11	11.61	0.001	0.07	8.20	0.005
Anterior midbody	0.13	13.87	0.001	0.09	10.15	0.001		NS
Posterior midbody	0.04	4.12	0.05		NS			NS
Isthmus	0.14	15.61	0.001	0.05	5.46	0.03		NS

Degrees of freedom: age (1,93), group (1, 92), age × group (1,91).

NS, not significant.
