IE first uses ME to grade the proportion of fundic crypt openings and then applies WLE features to classify H. pylori status. A prospective cohort (between 1 May 2024 and 30 December 2024; n\u2009=\u2009221) applied the locked IE algorithm and compared its performance with WLE and ME. The primary outcome was overall diagnostic accuracy; secondary outcomes were accuracy for each infection status category.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In the retrospective cohort, IE achieved higher overall accuracy than WLE and ME (79.8% vs 69.9% and 71.8%, respectively), with improved accuracy for negative (85.4%) and eradicated status (72.5%). ME was more accurate than WLE for negative (82.9% vs 61.0%) and eradicated status (62.7% vs 52.9%), whereas WLE was more accurate for positive status (87.3% vs 71.8%). In the prospective cohort, IE again showed the highest overall accuracy (86.4% vs 70.6% for WLE and 72.9% for ME), with higher accuracy for negative (90.7%) and eradicated status (92.4%), while WLE maintained higher accuracy for positive status (89.8% vs 78.4% for IE).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>IE that combines ME-based fundic crypt opening assessment with WLE features may improve endoscopic classification of overall, negative, and eradicated H. pylori infection status compared with WLE or ME alone.
