1 · What the graph read from it

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.

2 · The registry

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

Smouldering disease in multiple sclerosis (MS) refers to chronic central nervous system processes that occur beyond acute inflammation, driving long-term disability. Although current therapies effectively reduce relapse rates and MRI lesions, many individuals experience progression independent of relapse activity. While clinical progression is uncommon during childhood or adolescence, growing evidence suggests that subclinical progressive disease biology is already active even in this young age group, warranting early intervention to preserve function. Conventional MRI, while critical for diagnosis, lacks sensitivity for subtle damage. Advanced MRI techniques, including detection of chronic active lesions, global and focal brain damage, hold promise for early identification. Fluid biomarkers, such as neurofilament light chain and glial fibrillary acidic protein, provide non-invasive measures of neuroaxonal injury and ongoing chronic inflammation. This review summarises the role of MRI and fluid biomarkers in detecting smouldering disease in paediatric-onset MS and their application in supporting therapeutic decision-making.
