Clinical and demographic characteristics of the patients.

Patients were grouped based on relapses and EDSS changes during a two-year follow-up period. Pre-treatment parameters were similar between these groups, although disease duration tended to be longer for the “good” patient group. Mean ± standard deviation and t-test p-values are given for age, disease duration, EDSS at baseline and the number of relapses in the year before the gene expression measurement. The female to male ratio was compared by Fisher's exact test.
