Plasma p-Tau217 and GFAP predict widespread cognitive decline in Alzheimer's disease.
Article in Journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionProgression in Alzheimer's disease (AD) involves three main interrelated biological axes-tau deposition, neurodegeneration, and neuroinflammation-that jointly drive cognitive decline. Although several cerebrospinal fluid (CSF) and plasma biomarkers along these axes are well validated for diagnosis, their value for prognosis remains uncertain. We assessed how baseline markers of each axis predict cognitive trajectories in biomarker-confirmed AD.
methodsWe included 136 A + T + N + individuals (median follow-up = 24 months [IQR 12-24]; mean = 17.6 months [SD = 12.4]). Tau-deposition markers (CSF p-Tau181; plasma p-Tau181 and p-Tau217), neurodegeneration markers (CSF t-Tau; CSF and plasma neurofilament light chain, NfL) and a neuroinflammation marker (plasma glial fibrillary acidic protein, GFAP) were quantified using CLEIA, ELISA or Simoa, and stratified into tertiles. Participants were classified by age at onset, clinical phenotype, and APOE ε4 status. Cognition was assessed annually with a comprehensive neuropsychological battery. Linear mixed-effects models (MMRM) were used to test biomarker-cognition associations and interactions with clinical variables.
resultsElevated CSF p-Tau181 and NfL levels were associated with greater decline in memory and executive function. Among plasma biomarkers, p-Tau217 and GFAP showed the strongest associations with widespread cognitive decline, particularly in language, visuospatial, and executive domains. These associations were independent of age at onset, clinical phenotype, and APOE ε4 status. DISCUSSION/
conclusionOur findings highlight the potential prognostic value of fluid biomarkers in AD, especially CSF p-Tau181 and NfL, and plasma p-Tau217 and GFAP. These results suggest promise for improving disease monitoring, although prognostic utility at the individual level remains uncertain.
