Massive study tests if insurance records can mimic Gold-Standard drug trials

NCT ID NCT04736420

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at healthcare claims from over 78,000 people to see if it can reproduce the results of the EINSTEIN-DVT trial, which compared two blood thinners (rivaroxaban and warfarin) for treating blood clots. The goal is not to test a new drug, but to learn whether real-world data can reliably mimic clinical trials. If it works, this approach could help researchers answer questions faster and cheaper using existing health records.
