Table 2.

The performance of the anomaly detection model in detecting abnormal fundus images in the internal and external test sets.

Test data sets	Area under the receiver operating characteristic curve (95% CI)a	Proportion (%) (95% CI)b
		Accuracy	Sensitivity	Specificity
Internal test set	0.896 (0.891- 0.900)	82.67 (82.10-83.22)	82.69 (81.94-83.42)	82.63 (81.74-83.49)
Local-2	0.900 (0.893-0.906)	83.35 (82.63-84.04)	83.25 (82.52-83.97)	85.19 (81.90-88.07)

^aThe binomial exact 95% CI was calculated for each are under the receiver operating characteristic curve.

^bThe Wilson score was applied to calculate the Wilson 95% CI for accuracy, sensitivity, and specificity.
