NCT ID NCT07037940
First seen Jun 25, 2026 · Last updated Aug 12, 2026 · Updated 3 times
Summary
This study tested two AI tools—OpenEvidence and GPT-4 (ChatGPT)—to see which one helps doctors make better diagnoses and treatment decisions. Twenty-seven internal medicine doctors used both tools on medical cases. The goal was to compare how accurate and fast each AI made them. Results are still being analyzed.
