Massive european data merge aims to unlock blood clot mysteries
NCT ID NCT07328152
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is not testing a new drug or treatment. Instead, researchers are combining health information from 20,000 people across 14 European groups who have had blood clots (venous thromboembolism). By merging this data, they hope to better understand who is at risk for future clots, bleeding, or death. The goal is to improve how doctors predict and manage these conditions.
