Fig 2. Receiver operating characteristic curves of the algorithm and the dermoscopic examination.

The area under the curve (AUC) value of the algorithm was 0.751 (95% CI, 0.646–0.856), whereas the AUC value of dermoscopic examination was 0.755 (95% CI, 0.654–0.855). The results of the reader test are shown as circles (board-certified dermatologists).
