Comparison of physician-adjudicated definite stroke, self-reported stroke, and overt and covert MRI-defined vascular brain injury, for 817 American Indian participants of the Strong Heart Study (2010–2013)

		Definite Adjudicated stroke
		(Yes) N=33	(No) N=784
Self-reported stroke	(Yes) N=68	25	43
Self-reported stroke	(No) N=749	8	741
Sensitivity 75.8%, specificity 94.5%, correct classification 93.8%, AUC 0.85
MRI-defined vascular brain injury^‡	(Yes) N=287	24	263
MRI-defined vascular brain injury^‡	(No) N=530	9	521
Sensitivity 72.7%, specificity 66.5%, correct classification 66.7%, AUC 0.70

^‡

MRI-defined vascular brain injury (N=287) includes cerebral infarcts ≥ 3 mm (N=263) and hemorrhage any size (N=45). These categories are not mutually exclusive, with N=21 having both infarcts and hemorrhages.
