LIGHT/TNFSF14 Levels in Carotid Plaques Are Associated With Symptomatic Cerebrovascular Disease.
Article in Journal of stroke, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
background and purposePlaque rupture is the underlying cause of most cardiovascular events, such as stroke and myocardial infarction. The co-stimulatory molecule LIGHT (tumor necrosis factor superfamily member 14, TNFSF14) has been detected in foam cell-rich regions of atherosclerotic plaques, but whether it has a role in plaque stability is not known. This study investigates the association between intraplaque LIGHT levels and plaque vulnerability.
methodsLIGHT levels were measured in homogenates of carotid endarterectomy samples by proximity extension assay (n=202) and through bulk RNA sequencing and spatial transcriptomics (Visium) of plaques from patients included in the Carotid Plaque Imaging Project. Homogenates were further examined by multiplex analyses and enzyme-linked immunosorbent assay, and plaque sections by immunohistochemistry.
resultsPlaque levels of LIGHT were associated with occurrence of preoperative cerebrovascular symptoms, including stroke. LIGHT levels correlated with a histological plaque vulnerability index, necrotic core size, and inflammatory cytokine levels. Additionally, expression of extracellular matrix turnover machinery components, including the collagen cross-linking proteoglycan fibromodulin and matrix metalloproteinases 1, 2, 9, and 10, was associated with plaque LIGHT levels.
conclusionExpression of LIGHT in atherosclerotic plaques not only correlates with markers of plaque destabilization, but is also significantly elevated in plaques from symptomatic compared to those from asymptomatic patients. These results associate LIGHT content with a rupture-prone plaque phenotype, potentially upregulated as part of a reparative response, warranting further studies.
