^‡ Ratio of male to female patients included in the study; ratio of * clinically isolated syndrome patients to ^†clinically definite MS patients; number of patients presenting with ^§ mono-focal versus multi-focal optic neuritis as a CIS at baseline; ^10# number and percentage of abnormal magnetic resonance imaging scans at presentation; ^9** number and percentage of patients with positive oligoclonal bands in their cerebrospinal fluid analysis at baseline:  ̂‌  number and percentage of patients who received treatment with the equivalent of 1000 mg intravenous methylprednisolone for three days for acute optic neuritis.
