Fig. 2: Performance validation of the artificial intelligence model and pathologists in the interpretation of confocal laser endomicroscopic images.

a Confusion matrix illustrating the performance of the artificial intelligence (AI) model in interpreting images from the confocal laser endomicroscopic system (CLES) in the external validation dataset. b Confusion matrices depicting the performance of pathologists in interpreting CLES images in the external validation dataset. c Confusion matrices representing the performance of pathologists before (upper row) and after (lower row) AI assistance in interpreting CLES images in the external validation dataset. d Sankey diagrams illustrating the interpretation of CLES images by the four pathologists before and after AI assistance.
