There were no significant differences in the baseline characteristics of patients with and without Month 24 or ET visits; baseline characteristics were compared using the 2-sided Mann-Whitney test (quantitative variables) or 2-sided Fisher’s exact test (qualitative variables). aPercentages add up to values slightly above 100% (100.1%) due to rounding up to one decimal place. DMD, disease-modifying drug; EDSS, Expanded Disability Status Scale; ET, early termination; MS, multiple sclerosis; SD, standard deviation.
