Locus coeruleus-entorhinal cortex tract integrity is linked to plasma tau and glial fibrillary acidic protein.

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
introductionPretangle tau inclusions from the locus coeruleus (LC) are hypothesized to propagate to the entorhinal cortex (EC) via neuron-to-neuron transmission along its projections. The lower integrity of the LC-EC pathway accompanying Alzheimer's disease (AD) pathology is supported by post mortem studies, but in vivo evidence remains limited.
methodsWe associated diffusion-weighted 7T magnetic resonance imaging (MRI) metrics of microstructural integrity within the LC-EC tract to plasma AD-related biomarkers in a cohort of 47 cognitively unimpaired adults.
resultsWorse overall and local LC-EC integrity, indicated by lower fractional anisotropy (FA) and higher mean diffusivity (MD), was related to elevated concentrations of plasma phosphorylated tau 181 (p-tau181), p-tau217, and glial fibrillary acidic protein (GFAP). A higher orientation dispersion index (ODI) within the LC-EC tract was linked to elevated plasma p-tau181 and p-tau231 levels. DISCUSSION: The lower integrity of the LC-EC pathway may serve as a key indicator of the earliest AD-related pathophysiological processes to improve detection of at-risk individuals. HIGHLIGHTS: Standard DTI model metrics in the LC- EC tract are linked to elevated plasma p-tau and GFAP. A higher ODI in the voxels containing the LC-EC tract is related to elevated plasma p-tau. LC-EC integrity links to AD-related biomarkers show topographic specificity. Lower LC-EC integrity may be a key indicator of the earliest AD-related pathology.
