What is a Core Outcome Set?
A Core Outcome Set (COS) is an agreed minimum set of outcome domains and corresponding measurement instruments that should be measured and reported in all clinical trials or studies for a specific health condition or intervention. These sets ensure consistency, comparability, and relevance of research findings across studies.
