TABLE 2:

Correlations between mean diffusivity histogram-derived measures and Rankin disability score and T2 lesion load in patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy

		Rankin Score	T2 Lesion Load
Average D̄ of WBP	Fluid-suppressed	SRCC = 0.308, ns	r = 0.928^*
	Standard	SRCC = 0.660^†	r = 0.859^*
Average D̄ of NAB	Fluid-suppressed	SRCC = 0.307, ns	r = 0.786^*
	Standard	SRCC = 0.741^*	r = 0.743^*
Δ av D̄	WBP	SRCC = 0.915^*	nd
Δ av D̄	NAB	SRCC = 0.889^*	nd

Note.—D̄ indicates mean diffusivity; WBP, whole brain parenchyma; SRCC, Spearman’s rank correlation coefficient; ns, not significant; r, Pearson’s correlation coefficient; NAB, normal appearing brain; Δ av D̄ = average mean diffusivity from standard images; nd, not done.
* Significant at the Bonferroni-corrected level.
† Significant at the uncorrected level.
