Performance of single-tensor and multi-compartment integrity measures to account for age-related variance were compared using forward likelihood ratio logistic regression. Hindered and free diffusion measures captured the most age-related variance. All other predictors were excluded from the model

Model	Variable	B	S.E.	Wald	Sig.	Negelkerke R square
1	Hindered	61.799	20.07	9.481	0.002	0.366
2	Free	37.101	12.511	8.794	0.003	0.643
	Diffusion
	Hindered	78.046	24.063	10.519	0.001

Predicted Variable: Age, dichotomized. B = Intercept, S.E.= Standard Error, Wald = Wald chi-square test, Sig.= Significance.
