Metabolism fluctuation coupling can track the progression of dementia and describe MST1 gene-related pathology.

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
backgroundCognitive resilience refers to an individual's capacity to cope with brain aging and pathology and to delay cognitive decline, whereas existing techniques such as functional magnetic resonance imaging capture only macroscopic features without linking them to neurophysiological mechanisms. Recent studies have shown that overexpression of the MST1 gene exacerbates Alzheimer's disease phenotypes by affecting neuronal activity and metabolism; however, its association with cognitive trajectories and imaging biomarkers remains to be further investigated.
methodsMultimodal imaging data using information from 116 individuals with mild cognitive impairment was obtained from the ADNI database and participants from the HABS database. The correlation coefficient between glucose metabolism and neuronal low-frequency fluctuations was calculated, and residuals were derived from regression models of correlation coefficient with amyloid protein. Unsupervised clustering was then applied, and mediation analysis was conducted to investigate the mediating role of limbic orbital frontal cortex residuals in the association between MST1 gene expression and cognitive trajectories.
resultsClustering identifies five groups with distinct cognitive trajectories: the high and low cognitive resilience groups exhibit slower dementia progression with lower MST1 expression, whereas the high and low cognitive vulnerability groups show faster dementia progression with higher MST1 expression. No significant differences are observed in glucose metabolism or amyloid protein levels across groups, while the limbic orbital frontal cortex residuals partially mediate the effect of MST1 gene expression on cognitive trajectories.
conclusionsResidual biomarkers can track dementia progression and characterize MST1-related pathology, providing imaging markers for assessing cognitive resilience and monitoring disease at the molecular level.
