Disease outcomes following lateral switch among different CD20-antibodies in active multiple sclerosis.
Article in Multiple sclerosis (Houndmills, Basingstoke, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundOcrelizumab (OCR) and ofatumumab (OFA)are approved and their differences in dosing route and interval allow personalized treatment. However, there are no data on whether lateral switches between both substances affect treatment effectiveness or safety.
methodsWe screened our local cohort of MS patients, who began OCR since 09/2020 or OFA since 09/2021. Patients with a lateral switch were matched to controls who continuously received initial B-cell depleting therapy (BCT). We compared disease courses including effectiveness outcomes as well as peripheral CD19+ B-cell counts and serum IgG levels.
resultsFrom 09/2020 to 03/2024, 713 patients were subjected to BCT (OCR: 396; OFA: 317 [as in Fig.1]). The matched OCR cohort included 38 switchers and 149 controls. The OFA cohort consisted of 24 switchers and 83 controls. Effectiveness outcomes were comparable among switchers and controls. B cell depletion appeared slightly pronounced following a switch. Serum IgG levels declined faster among switchers compared to controls (OCR: 9.7 vs 9.0 g/L;
conclusionsLateral switching between BCT does not abate effectiveness in this matched real-world cohort. Our observation of increased loss of IgG warrants further validation, but may indicate niche-specific immunological effects of OFA and OCR.
