The diagnostic performance comparison between DL group and endoscopist group when taking pathological diagnosis as the gold standard. A Partial AUC (The black shaded part) at the sensitivity ≥ 0.8 for DL group. B Partial AUC (The dark grey shaded part) at the sensitivity ≥ 0.8 for endoscopist group. C Partial AUC ((The black shaded part) at the specificity ≥ 0.8 for DL group. D Partial AUC (The dark grey shaded part) at the specificity ≥ 0.8 for endoscopist group. E ROC curves for DL group and endoscopist group respectively. After matching and taking pathological diagnosis as the gold standard, the diagnostic evaluation indices and the evaluation of consistency with pathological diagnosis in the DL group were better than those in the endoscopist group
