Omics-derived biological modules reflect tau positron emission tomography in Alzheimer's disease.
Article in Alzheimer's & dementia (New York, N. Y.). 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
backgroundTau neurofibrillary pathology is a hallmark of Alzheimer's disease (AD) and can be quantified in vivo using tau-selective positron emission tomography (tau PET). Tau PET signal closely correlates with cognitive decline and disease stage, yet the molecular networks underpinning tau accumulation remain incompletely defined.
methodsWe performed multi-omics integration of proteomics, transcriptomics, and tau PET standardized uptake value ratios (SUVRs), and clinical assessments data from cognitively normal and cognitively impaired individuals. Using Light Gradient Boosting Machine (LightGBM), two-way orthogonal partial least squares, and network-based approaches, we explored key tau-associated proteomic signatures and constructed protein-protein interaction (PPI) modules. Module activities were quantified by gene set variation analysis and related to tau PET and cognition.
resultsAmong 60 regions, 15 tau PET imaging biomarkers were selected based on group differences, LightGBM importance, and cognitive relevance. Fifty key tau-associated proteins were identified and organized into four functional modules. PPI modules 1 (metabolic-cytoskeletal) and 3 (adhesion-nutrient sensing) exhibited strong associations with elevated tau PET uptake across selected cortical and limbic regions, as well as with cognitive impairment.
conclusionDistinct modules reflected regional tau PET burden and cognitive outcomes in AD, highlighting convergent disruptions in energy metabolism, cytoskeletal stability, and intercellular signaling. Highlights: Integration of proteomics, transcriptomics, tau positron emission tomography (PET) imaging, and cognition in Alzheimer's disease.Fifteen key tau PET imaging biomarkers were prioritized.Fifty key tau-associated proteins were identified.Four distinct molecular networks contribute to regional tau pathology and cognition.Modules 1 (metabolic-cytoskeletal) and 3 (adhesion-nutrient sensing) strongly associated with tau PET burden and cognitive impairment.
