Risk of stroke under disease modifying therapies for multiple sclerosis: a systematic review.
Review in Therapeutic advances in neurological disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Epidemiological research indicates a heightened incidence of cerebrovascular disorders among patients with multiple sclerosis (MS). Objectives: The aim of the present systematic review was to investigate the potential association between disease modifying therapies (DMTs) and the risk of stroke in MS patient populations. Data sources and methods: A systematic literature search was performed in MEDLINE and SCOPUS databases up to April 6, 2024, to identify randomized-controlled clinical trials (RCT), registry-based and cohort-studies, case-series, and case-reports reporting on acute ischemic stroke (AIS) or intracerebral hemorrhage (ICH) in MS patients under different DMTs. Results: Twenty-one studies were included: 1 RCT, 6 registry-based or cohort studies, 2 case-series and 11 case-reports. Overall, DMTs appear to reduce the risk of stroke in MS patients, with DMT exposure linked to a 50% reduction of the risk of stroke compared to no DMT exposure. Although glatiramer acetate and dimethyl fumarate appear to lower the risk of stroke, concerns about fingolimod exists due to an observed elevated risk for ischemic heart disease and hypertension. Despite the absence of detected safety concerns with alemtuzumab at the MS population level, alemtuzumab-related complications, although rare, signal the need for heightened clinical vigilance. Similarly, β-interferons have been linked to life-threatening adverse events, comprising thrombotic thrombocytopenic purpura-hemolytic uremic syndrome (TTP-HUS). No associations between the risk of stroke and other DMTs, comprising natalizumab and teriflunomide, were detected; yet, newly approved DMTs were underrepresented. Conclusion: These findings highlight the importance of personalizing DMT selection and monitoring cardiovascular risk factors to reduce stroke risk in patients with MS. Trial registration: PROSPERO CRD42024534470.
