Blood clot registry aims to uncover hidden risk factors
NCT ID NCT02188056
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed study followed 300 patients with venous thromboembolism (blood clots in veins) to track how often clots return or cause bleeding. Researchers hope to find new risk factors and compare newer blood thinners. The study only observes, so it cannot test treatments directly.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this registry could help identify new risk factors for blood clots and improve treatment comparisons.
- What could go wrong
- This is an observational study, not a treatment trial, so it cannot prove cause and effect. Results may not apply to all patients.
