Two Years of Ocrelizumab Treatment in Black and Hispanic People with Multiple Sclerosis in CHIMES: A Single-Arm Clinical Trial.
Trial report in Annals of neurology, 2026. 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
objectiveTo evaluate the effectiveness and safety of ocrelizumab in self-identified black and Hispanic people with relapsing multiple sclerosis.
methodsThe Characterization of Ocrelizumab in Minorities with Multiple Sclerosis (CHIMES) trial, a prospective, open-label, single-arm, phase 4 study, intentionally recruited underrepresented populations in the US, Puerto Rico, and Kenya. Black and Hispanic people with relapsing multiple sclerosis aged 18-65 years with Expanded Disability Status Scale score 0-5.5 received ocrelizumab for 2 years. The primary endpoint was the proportion of participants with no evidence of disease activity in 3 components at week 48: protocol-defined relapse, 24-week confirmed disability progression, and disease activity on magnetic resonance imaging.
resultsOf 113 black and 69 Hispanic people with relapsing multiple sclerosis, most were women (72%), with a mean age of 35.5 (SD 10.5) years, body mass index of 31.0 (SD 7.4) kg/m
interpretationOcrelizumab treatment controlled disease activity in black and Hispanic people with relapsing multiple sclerosis. Results were consistent with pivotal ocrelizumab trials, supporting ocrelizumab's effectiveness and tolerability in these populations. ANN NEUROL 2026;100:793-807.
