Deep Plasma Proteomics-Based Diagnostic Panel for Early Detection of Amnestic Mild Cognitive Impairment.
Article in Journal of proteome research, 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
Amnestic mild cognitive impairment (aMCI) is often considered an early clinical stage of Alzheimer's disease (AD), but its subtle presentation leads to infrequent neurological evaluations. Early plasma biomarker screening during routine check-ups in community hospitals could enhance aMCI detection rates. Advances in proteomics, particularly mass spectrometry, have enabled the detection of low-abundance plasma proteins, opening new possibilities for aMCI biomarker identification. This study included 84 participants from the STAR cohort. We utilized deep plasma proteomics to detect low-abundance proteins, enriched with nanoparticle magnetic beads. An early diagnostic model for aMCI was developed through bioinformatics and machine learning, with performance compared to the Simoa assay. We identified 4268 low-abundance plasma proteins and constructed a 12-protein diagnostic panel (AUC = 0.992 in the training set, AUC = 0.933 in the testing set), outperforming the Simoa assay (accuracy: 93.9% vs 24.4%). In conclusion, the 12-protein panel provides a cost-effective method for early aMCI detection, potentially improving screening efficacy.
