"Registry-based non-randomized studies for treatment comparisons"
Symposium
The project NANA team from the Department of Medical Statistics, University Medical Center Göttingen, is pleased to announce a symposium on current methods for registry-based non-randomized studies for assessing the benefits and harms of drugs and other medical interventions to support decision making (e.g., regulatory and Health Technology Assessment).
The symposium will be held on 26th of May 2026 from 11 am – 5 pm in Göttingen.
We will discuss insights and results from the NANA project and invited speakers will share their experiences and innovative methodological approaches at the intersection of statistics, data requirements, and regulatory requirements.
