ROC Curves Indicating the Contrast With Trails B for Each UFOV Subtest and Risk Index (N = 198)

Contrast	Estimate	Standard Error	95% Confidence Interval	p
UFOV RI–Trails B	.13	.05	[.02, .23]	.02
UFOV 1–Trails B	.02	.06	[–.11, .15]	.76
UFOV 2–Trails B	.09	.053	[–.02, .19]	.09
UFOV 3–Trails B	.02	.075	[–.12, .17]	.76

Note. The estimate is derived from subtracting the AUCs of the test indicated in the Contrast column. ROC = receiver operating characteristic; AUC = area under the curve; UFOV = Useful Field of View; 1 = Subtest 1; 2 = Subtest 2; 3 = Subtest 3; RI = Risk Index.
