EOS is defined as the last assessment taken on or before the final study phase visit date. n, number of patients included in each analysis.
*Obtained from fitting a negative binomial regression model adjusted for treatment, region, pubertal status (the stratification factor in IVRS), subgroup, subgroup-by-treatment interaction and baseline number of T2 lesions (offset: time in study).

DMT, disease-modifying therapy; EOS, end of the study; FAS, full analysis set; IFN, interferon; IVRS, interactive voice response system.
