Neuroimaging spectrum of myelin oligodendrocyte glycoprotein antibody-associated disease with brain involvement: description of various cerebral syndromes.

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
backgroundMyelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is a notable cause of acquired central nervous system inflammatory disorders in children.
objectiveThis study aimed to characterize the neuroimaging spectrum of pediatric MOGAD with brain involvement. MATERIALS AND
methodsIn this retrospective, single-center study, 55 children diagnosed with MOGAD involving the brain between January 2010 and October 2020 were included. Clinical data and neuroimaging-brain and spinal magnetic resonance imaging (MRI) at presentation-were reviewed. Imaging patterns were categorized into six radiologic phenotypes: acute disseminated encephalomyelitis (ADEM), cerebral cortical encephalitis, aseptic meningitis, tumefactive demyelinating lesion, cerebellitis/brainstem encephalitis, and miscellaneous. Imaging features were further analyzed in the ADEM subgroup.
resultsADEM was the most common phenotype (39 of 55 patients, 71%), though atypical features were frequent, with 62% showing at least one atypical MRI finding. Unlike classic ADEM with large confluent white matter lesions, MOGAD-associated ADEM often showed small (31%) or subcortical (44%) white matter lesions. Spinal lesions typically appeared as longitudinally extensive myelitis with central gray matter involvement. Other phenotypes included cortical encephalitis (three patients), aseptic meningitis (six), tumefactive demyelinating lesions (three), cerebellitis/brainstem encephalitis (two), and two miscellaneous patterns. Non-ADEM phenotypes presented at an older age than ADEM (11.5 years vs. 5.2 years, P < 0.01), with a threshold of 7.6 years.
conclusionPediatric MOGAD with brain involvement presents a range of imaging patterns. ADEM is most frequent but often displays atypical features. Non-ADEM phenotypes tend to occur in older children.
