Interaction of metabolic and inflammatory dysregulation on central degeneration and cognitive function in behavioral variant Frontotemporal dementia.
Article in Journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundMetabolic and inflammation dysregulation are important mechanisms in neurodegenerative diseases, but their study in behavioral variant frontotemporal dementia (bvFTD) is very scarce; we aimed to investigate the separate and interactive effects of metabolic and inflammatory dysregulation on central degeneration and cognitive function in patients with bvFTD.
methodsThis study recruited participants with bvFTD and healthy controls (HC) from December 15, 2017, to September 5, 2024, in the Department of Neurology of Xuanwu Hospital, underwent assessment of plasma targeted metabolite, plasma inflammatory factors, 18F-fludeoxyglucose-positron emission tomography/magnetic resonance imaging, and neuropsychological assessments. Linear regression models and interaction models were implemented using age, sex and education level as covariates to explore the association between differential metabolites and peripheral inflammatory markers with neuroimaging, and clinical measures.
resultsForty bvFTD patients and 40 HC (56.25% female, mean age of 63.55 years) were involved. A total of 36 plasma differential metabolites were screened out with variable importance in projection (VIP) > 1 and p < 0.05. Differential metabolites distributed in metabolic pathways that regulate inflammation, such as Aminoacyl-tRNA biosynthesis, mTOR signaling and amino acid metabolism. Furthermore, differential metabolites and plasma inflammatory factors are correlated with atrophy and glucose metabolism in certain frontal-temporal brain regions, as well as cognitive function (p < 0.05). Additionally, the interaction between differential metabolites and inflammatory factors is associated with atrophy and glucose metabolism in the entire frontal-temporal brain region, as well as cognitive function (p < 0.05). Under conditions of dysregulation of inflammatory factors such as Interleukin, Interferons, and Tumour necrosis factor, metabolites in Aminoacyl-tRNA biosynthesis, mTOR signaling, and amino acid metabolism have a more pronounced impact on frontotemporal lobar degeneration and cognitive symptoms (p < 0.05).
conclusionsThis study shows that bvFTD exhibits peripheral metabolic and inflammatory dysregulation, which are associated with frontotemporal lobar degeneration and clinical symptoms, and the interaction effects of metabolic and inflammatory dysregulation have a greater impact on bvFTD.
