Statistical comparison of diagnostic performance between ECMAI-ME and endoscopists. Pairwise comparisons were performed between ECMAI-ME and six endoscopists. (a) Accuracy. (b) Specificity for non-GISTs. (c) Sensitivity for GISTs. Values above the bars indicate performance differences; ↑ indicates higher and ↓ lower performance relative to ECMAI-ME. Corresponding p-values are shown above each bar. Abbreviations: GISTs, gastrointestinal stromal tumors.
