Identification and validation of a pyroptosis-related gene signature in intracranial aneurysm.
Article in Open life sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Intracranial aneurysm (IA) is a life-threatening cerebrovascular disorder, the underlying molecular mechanisms of which remain incompletely elucidated. Pyroptosis, a pro-inflammatory form of programmed cell death, has been implicated in various vascular pathologies. However, its role in the pathogenesis of IA remains largely unclear. In this study, we identified and validated a pyroptosis-related gene signature linked to IA using GEO dataset. Differential expression analysis and pathway enrichment methods revealed key pyroptosis-related markers, including CASP8, NOD2, PYCARD, which were strongly associated with IA progression. Functional analysis highlighted their involvement in inflammatory and immune pathways, particularly in promoting vascular remodeling through pyroptosis-driven mechanisms. Machine learning approaches refined these markers into a robust predictive signature. Validation in independent cohorts confirmed their diagnostic and prognostic potential for IA. Moreover, we validated the upregulation of these genes and found the activation of CASP8 in clinical IA samples. Our findings provide novel insights into the molecular underpinnings of IA, offering a framework for the development of pyroptosis-based biomarkers and therapeutic strategies aimed at early detection and targeted intervention in IA management.
