Table 4.

Quantitative comparison of the proposed workflows in terms of the requirements for pathologist review as fraction of the current reviewed cases, TFF3 staining as fraction of the current cases, observed prevalence of BE, sensitivity and specificity (with 95% CIs in parentheses)

Proposed ML-assisted workflow	Pathologist review	TFF3 staining	Observed prevalence	Sensitivity	Specificity
Pathologist reviews any positives	48% (41–55%)	100%	17% (14–20%)	1.00 (1.00–1.00)	1.00 (1.00–1.00)
Pathologist reviews H&E model positives	37% (31-45%)	37% (31–45%)	19% (16–24%)	0.91 (0.84–0.96)	1.00 (1.00–1.00)
