Transcriptomic decoding of regional cortical vulnerability to drug-resistant epilepsy using 7T MRI.
Article in Communications biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
The mechanism by which genetic risk leads to cortical vulnerability in drug-resistant epilepsy (DRE) remains unclear. This study used 7T structural and resting-state functional MRI to investigate cortical neural activity alterations in 105 DRE patients and 105 healthy controls (HCs), and to explore related genetic mechanisms. Vertex-wise analyses of mean amplitude of low-frequency fluctuation (mALFF) and regional homogeneity (ReHo) revealed that DRE patients primarily exhibited decreased mALFF and increased ReHo in the Cingulo-Opercular Network. Using the Allen Human Brain Atlas, we conducted spatial transcriptomic analysis via partial least squares (PLS) and gene enrichment analysis to identify gene categories associated with these functional changes. The results showed that cortical alterations were related to epilepsy-general genes (e.g., TMEM74, KCNN2, RBFOX1) and brain-relevant genes. Genes positively correlated with mALFF alterations enriched in mitochondrial inner membrane, matrix, and carboxylic acid metabolism; negatively in chromatin remodeling, binding, and postsynapse. Genes positively correlated with ReHo alterations enriched in nucleic acid-related catalytic activity, ribonucleoprotein granule, and centrosome; negatively in amyotrophic lateral sclerosis, mitochondrial membrane, and pyrophosphatase activity. These findings link spatial brain activity abnormalities in DRE to specific genetic signatures and biological pathways, suggesting new mechanistic insights and potential therapeutic targets for this difficult-to-treat condition.
