Sensitivity and specificity were pooled for internal and external validation sets. The comparison between DL algorithms and expert endoscopists was performed using paired forest plots. Meta-regression was used to identify sources of heterogeneity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In the internal validation, 15 studies comprising 37,037 images (range: 433\u20139,650) were included. Pooled sensitivity and specificity were 0.91 (95% CI: 0.82\u20130.95) and 0.93 (95% CI: 0.87\u20130.97), respectively. Meta-regression showed that heterogeneity in sensitivity and specificity was significantly associated with training dataset size. For external validation, 4 studies with 3,579 images (range: 200\u20131,514) were included, yielding pooled sensitivity and specificity of 0.82 (95% CI: 0.61\u20130.93) and 0.83 (95% CI: 0.74\u20130.90), respectively. No significant difference was observed between deep learning models and expert endoscopists in diagnostic sensitivity and specificity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Deep learning algorithms exhibit high diagnostic performance in detecting early gastric cancer using white-light endoscopy.
