Advancing Real-World Evidence Through a Federated Health Data Network (EHDEN): Descriptive Study

This is the authors' abstract. We don't add key points for this paper.

EHDEN is the largest federated health data network in Europe, enabling standardized, General Data Protection Regulation-compliant analysis of RWD across diverse care settings and populations. This descriptive summary of the network's data sources enhances transparency and supports broader efforts to scale federated research. These findings demonstrate EHDEN's potential to enable collaborative studies and generate trusted evidence for public health and regulatory purposes.
