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

objectivePrevious longitudinal neuroimaging studies suggest that epilepsy is a progressive disorder. To date, these findings have relied largely on populations from tertiary centers, resulting in ascertainment bias, as severely affected individuals are more likely to be rescanned. We aimed to determine rates of progressive brain atrophy in a prospective, population-based cohort.

methodsWe analyzed longitudinal magnetic resonance imaging (MRI) data from 116 individuals with epilepsy and 89 age- and sex-matched healthy controls recruited from a prospective, longitudinal, community-based cohort in the United Kingdom. All participants underwent 2 scans 3.5 years apart, regardless of seizure status. We quantified progressive changes in cortical thickness and subcortical volumes using state-of-the-art longitudinal morphometry.

resultsPeople with epilepsy exhibited accelerated but modest global grey matter volume (GMV) loss compared with controls (2.7 vs 2.4 ml/year; p = 0.01). This acceleration was associated with specific phenotypes: focal epilepsy, MRI-identifiable lesions, and ongoing seizures. In contrast, generalized epilepsy and seizure-free periods were associated with more stable global trajectories. Cortical regions identified as vulnerable were characterized by markedly accelerated thinning compared to controls (5.3 vs 3.4 μm/year; p < 0.001) and were pervasive across most epilepsy phenotypes.

interpretationEpilepsy is associated with progressive structural brain damage that exceeds normal aging, but the trajectory is heterogeneous. These prospective population-based data confirm that vulnerable regions show progressive atrophy, particularly in focal and lesional epilepsy and individuals with ongoing seizures.
