Integrating an evidence-based assessment of benefit and risk in disease-modifying treatment of multiple sclerosis.

Background: As results from an increasing number of clinical trials with disease-modifying drugs (DMDs) in multiple sclerosis (MS) become available, the challenge for the treating neurologist is how to decide on the appropriate therapy for an individual patient.

Objective: An International Working Group for Treatment Optimization in MS met to consider how the principles of evidence-based medicine (EBM) should be used to assess the current best evidence regarding the treatment of MS. This report summarizes the outcome from the workshop at which this topic was addressed.
