Diagnostic performance of unassisted gastroenterologists and AI-assisted gastroenterologists during the online modules. (A–C) Overview of the gastroenterologists with AI support (N = 6) and without AI support (N = 6) before training (A), after training (B), and at follow-up (C) relative to the overall AI ROC curves for Test Set 1 and Test Set 2, and both test sets combined. (D) Sensitivity, specificity, and accuracy scores of the unassisted gastroenterologists for Test Set 2 before the cross-over and their scores for Test Set 2 with AI support after the cross-over, and the scores of the AI model alone for Test Set 2. * p = 0.020, ** p = 0.024, *** p = 0.039.
