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
Early, non-invasive assessment of Alzheimer's disease (AD) progression remains a key challenge. This study evaluated whether nasal amyloid-β42 (Aβ42) levels reflect brain amyloid dynamics and cognitive decline. Nasal discharge from 161 individuals, ranging from cognitively unimpaired to AD dementia, was analyzed using ELISA, alongside neuropsychological assessments and amyloid PET imaging. Moderate nasal Aβ42 levels (9.53-11.10 pg/mL) were positively associated with PET amyloid burden and cognitive decline, identifying a critical transitional disease stage. Conversely, the highest Aβ42 levels showed weaker correlations, suggesting a non-linear progression. The pattern of nasal Aβ42 mirrored brain amyloid accumulation, which peaks and stabilizes in later disease stages. These findings highlight nasal Aβ42 as a promising, scalable biomarker for tracking AD pathology and offer the first evidence linking it with brain amyloid PET. This supports its potential use in both clinical and longitudinal research settings.
