Massive study tests if Real-World data can replace clinical trials for diabetes heart risk

This study looked at whether real-world data can be used to compare two diabetes drugs, tirzepatide and sitagliptin, for preventing heart attacks, strokes, or death in people with type 2 diabetes and heart disease. Over 49,000 participants were included, but the goal was not to find a new treatment—it was to see if this type of analysis can be trusted for future research. No new drug or treatment was given; the study simply analyzed existing data.
