Brain lesion characteristics in Chinese multiple sclerosis patients: A 7-T MRI cohort study.
Article in Annals of clinical and translational neurology, 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
objectivePrevalence, susceptibility genes, and clinical and radiological features may differ across different ethnic groups of multiple sclerosis (MS). We aim to characterize brain lesions in Chinese patients with MS by use of 7-T MRI.
methodsMS participants were enrolled from the ongoing China National Registry of Neuro-Inflammatory Diseases (CNRID) cohort. 7-T MRI of the brain was performed. Each lesion was evaluated according to a standardized procedure. Central vein sign (CVS) and paramagnetic rim lesions were identified. The characteristics of lesions at patient-level and at lesion-level from previous 7-T MRI literature were also summarized.
resultsWe included 120 MS patients. Their mean (SD) age was 34.6 (9.4) years. The female-to-male ratio was 1.7:1 and mean disease duration of patients with MS was 5.5 ± 6.1 years. The median EDSS score was 2 (range, 0-8). A total of 8502 lesions were identified with a median lesion count of 45 (IQR, 18-90) (range, 2-370). The median (IQR) percentage for these special locations were as follows: cortical lesions (CLs) 2.7% (0%-5.7%), juxtacortical lesions 16.2% (7.8%-25.7%), periventricular lesions 30.2% (17.2%-38.7%), and infratentorial lesions 5.8% (0.4%-11.9%). CLs occurred in 70 (58%) patients, accounting for only 443 (5%) of the total lesions. Out of the 443 CLs, 309 (69.8%) were leukocortical lesions. CVS appeared in 5392 (63%) lesions from 117 (98%) patients. 1792 (21%) lesions and 104 (87%) patients exhibited a paramagnetic rim.
interpretationOur study elaborated on the lesion features of Chinese patients with MS by use of 7-T MRI. Lesion burden is heavy in Chinese patients with MS. The median lesion count and proportion of PRL are high. The reported heavy lesion burden calls for ramping up regional and global efforts to care for MS patients. The management and research of Chinese population with MS needs to be further strengthened.
