Determining the metabolic profile measured using ultra-high pressure liquid chromatography associated with Beta Amyloid burden in the brain in individuals with mild cognitive impairment.
Article in Research square, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
As the world's population ages, Alzheimer's disease (AD), a progressive neurodegenerative disorder, is becoming more common. The current diagnoses for AD are not precise enough to identify the disorder when it is possible to cure. An early indicator of Alzheimer's is the assessment of beta-amyloid by positron emission tomography (PET) score, a substantial decrease in the brain's metabolomics. Furthermore, Metabolomics can be detected by UPLC (ultra-high pressure liquid chromatography). This study investigates the link between metabolic profiles and beta-amyloid load in AD in order to shed light on possible biomarkers for disease progression. The data from 59 people who have been diagnosed with moderate cognitive impairment (MCI) is extracted from the Alzheimer's Disease Neuroimaging Initiative (ADNI). This study uses ultra-high-performance liquid chromatography (UPLC) to investigate the correlation between baseline metabolic data and changes in amyloid PET scores. Seven metabolites, including DOPA, Methionine Sulfoxide (Met.SO), Tryptophan Betaine, choline, leucine, valine, and FA (18:2), seem to have a substantial connection with amyloid PET scores. These can be used as early indications of AD progression, especially Met.SO is particularly relevant when considering time interaction. Understanding the metabolic alterations associated with amyloid load can pave the way for future research incorporating metabolites into a therapeutic treatment that can be identified as crucial to the illness's progression.
