Multicentric, Randomized, Double-blind Versus Placebo Study Evaluating the Efficacy of Treatment With Cholecalciferol (Vitamin D3) for Delaying the Diagnosis of Multiple Sclerosis (MS) After a Clinically Isolated Syndrome (CIS). Comparison of Conversion Rates After 2 Years
Abstract
The main objective of this study is to evaluate the efficacy and tolerance of 2 years of treatment with cholecalciferol (vitamin D3) in patients with a clinically isolated syndrome at high risk for MS (CIS).
Conditions: Multiple Sclerosis.
Primary outcome: Conversion to MS yes/no.
Enrollment: 316 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 316 participants or records.
