The Danish Multiple Sclerosis Registry (DMSR) is an important source of real-world multiple sclerosis (MS) data which has been documenting cases of clinical isolated syndrome (CIS) and MS since 1956. The DMSR has formed the backbone of many important scientific publications both in Denmark and around the world.
Why this matters
The DMSR is the oldest operating nationwide MS registry in the world. Registries are powerful sources of data which power an array of different observational study types and provide important real-world data on treatment effectiveness.
