Investigating the Frequency and Outcome of Central Vein Sign and Paramagnetic Rim Lesions in Children With MOGAD.

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 AND
objectivesCentral vein sign (CVS) is a common feature in multiple sclerosis (MS) lesions, but its frequency in myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) varies significantly across studies. Paramagnetic rim lesions (PRLs) are described in MS, but not in MOGAD. Our goals were to evaluate the prevalence of PRLs and CVS in a large multicenter cohort of pediatric MOGAD. We compared CVS frequencies between acute vs remission phases, as well as with longitudinal dynamics of lesion evolution.
methodsIn this longitudinal retrospective multicenter study, clinical MRIs were assessed from pediatric patients with MOGAD, who had (1) ≥1 brain lesion, (2) susceptibility-based imaging (SBI), and (3) follow-up MRI at least 3 months apart. T2-weighted and fluid-attenuated inversion recovery sequences were analyzed for lesion detection and resolution. SBI was used to assess CVS and PRLs following North American Imaging in MS Cooperative criteria.
resultsA total of 65 patients and 130 scans were included. A total of 520 lesions were evaluated. The most common reason for lesion exclusion was size (n = 143, large confluent lesions, n = 122, <3 mm, n = 21). CVS was detected in 97 of 327 (29.7%) lesions, with 32 of 65 (49.2%) patients having at least 1 CVS+ lesion. Patients with ≥1 CVS+ lesion (32/65, 49.2%) had a higher number of lesions ( DISCUSSION: Lesion pathobiology in MOGAD is heterogeneous. CVS identified persistent rather than transient lesions, with resolution more common among CVS- lesions. The high frequency of confluent or multivein lesions limited the proportion suitable for CVS analysis. MRI timing influenced CVS detection, which was higher in remission, suggesting that time of acquisition contributes to variability across MOGAD studies. No PRLs were found, supporting their potential as biomarkers distinguishing MOGAD from MS.
