A new retrospective study evaluated ten Chest X-ray AI models across twelve datasets from six countries, including both public benchmarks and private institutional cohorts. The research found that while models like MAVL and MedKLIP showed the highest specificity at 95% sensitivity, their positive predictive value was low, indicating many false positives. Performance on institutional data was generally lower than on public benchmarks, suggesting that current evaluations may overstate real-world applicability. The study emphasizes the need for operating-point-aware evaluation and external validation on institutional data before deploying these AI models. AI
