TABLE 3.

The comparison of AUC difference for cross validation curve and risk factors curves.

Variables	AUC difference	95% CI		p value
		Lower limit	Upper limit
Occludin level versus NIHSS score	0.080	–0.107	0.268	0.402
Combined model versus NIHSS score	0.179	0.049	0.309	0.007
Combined model versus occludin level	0.099	0.018	0.179	0.016

AUC, area under the curve; NIHSS, National Institutes of Health Stroke Scale; 95% CI, 95% confidence interval. The AUC for combined model was calculated based on the prediction from the leave-one-out cross-validation (LOOCV) procedure. Bold values represent different categories and significant p values.
