HE-DMTs reduced the risk of relapse in people at both high and low risk of aggressive MS, with no evidence of differential treatment benefit. In the overall population, no evidence of a difference in disability outcomes between HE-DMT-treated and HE-DMT-untreated time was observed. However, among patients ever exposed to HE-DMT, disability worsening was less common while treated with HE-DMT.
Roos et al. (Sat,) studied this question.
