There were 8 ophthalmologists who graded Eye PACS-1 and 7 ophthalmologists who graded Messidor-2.AUC indicates area under the receiver operating characteristic curve.In A, for the high-sensitivity operating point, specificity was 93.4% (95% CI, 92.8%-94.0%) and sensitivity was 97.5% (95% CI, 95.8%-98.7%); for the high-specificity operating point, specificity was 98.1% (95% CI, 97.8%-98.5%) and sensitivity was 90.3% (95% CI, 87.5%-92.7%).In B, for the high-sensitivity operating point, specificity was 93.9% (95% CI, 92.4%-95.3%) and sensitivity was 96.1% (95% CI, 92.4%-98.3%); for the high-specificity operating point, specificity was 98.5% (95% CI, 97.7%-99.1%) and sensitivity was 87.0% (95% CI, 81.1%-91.0%).

Image subsets were chosen by randomly sampling from the set of all images at rates (determined a priori) of (0.2%, 2%, 10%, 20%, 30%, …, 100%).
