Clinical Risk Score for Predicting Vascular Dementia after Ischemic Stroke in Thailand

Table 4

Accuracy of the risk score.

Cutoff point	AuROC (95% CI)	Sensitivity (95% CI)	Specificity (95% CI)	PPV (95% CI)	NPV (95% CI)	LR+ (95% CI)
≥5	0.76 (0.69, 0.83)	72.9% (58.2, 84.7)	79.1% (71.0, 85.7)	56.5% (43.3, 69.0)	88.7% (81.4, 93.8)	3.5 (2.4, 5.1)

AuROC: area under receiver operating characteristic curve; PPV: positive predictive value; NPV: negative predictive value; LR+: likelihood ratio if test positive.
