De-Escalation Treatment Strategies From Natalizumab in Patients With Relapsing Multiple Sclerosis in Austria.
Article in European journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThis study aims to assess the efficacy of de-escalating from natalizumab (NTZ) to cladribine (CLAD), dimethyl fumarate (DMF), fingolimod (FTY), ponesimod (PONE), siponimod (SIPO) and teriflunomide (TERI). MATERIAL AND
methodsWe analyzed data from 388 patients in the Austrian MS Treatment Registry who initiated NTZ treatment and remained on therapy for at least 3 months before switching to one of the moderately effective therapies within 1 year. Patients were required to remain on the de-escalation therapy for at least 3 months.
resultsOver a mean treatment duration of 42 months, the estimated ARR (annualized relapse rate) was 0.22 for highly effective therapy and 0.36 for de-escalation therapies over 61 months (p = 0.009). EDSS scores increased significantly from 2.8 to 3.1 during de-escalation (p < 0.001). Relapse probability during the treatment gap varied by interval: 14 patients (5.2%) in the < 3 months group, 14 patients (15.7%) in the 3-6 months group, and 13 patients (39.4%) in the 6-12 months group (p < 0.001). Male sex, lower baseline ARR (prior to the initiation of hDMT) and during transition, older age, shorter disease duration, and lower EDSS scores at both baseline and post-transition were significantly associated with a reduced risk of relapse and longer time to first relapse following de-escalation.
conclusionsOur findings reveal an increased risk of relapses and EDSS worsening following de-escalation from NTZ. Additionally, relapse probability and EDSS progression were influenced by ARR during transition and EDSS scores at the end of the transition period.
