Preclinical dementia rating scores are associated with plasma phosphorylated tau-217.

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
introductionSimple screening tools are critical for assessing Alzheimer's disease (AD)-related pre-dementia changes. This study investigated longitudinal scores from the Quick Dementia Rating System (QDRS), a brief study partner-reported measure, in relation to baseline levels of the AD biomarker plasma pTau217 in individuals unimpaired at baseline.
methodsData from the Wisconsin Registry for Alzheimer's Prevention (N = 639) were used to examine whether baseline plasma pTau217 (ALZpath assay on Quanterix platform) modified QDRS or Preclinical Alzheimer's Cognitive Composite (PACC3) trajectories (mixed-effects models; time = age). pTau217*age interaction effects (e.g., high vs low pTau217 simple age slopes) were compared across outcomes.
resultsHigher baseline pTau217 levels were associated with faster functional (QDRS) and cognitive (PACC3) decline. Effect sizes were similar between PACC3 and QDRS. Exploratory analyses showed increased risk of transitioning to impaired QDRS classifications in those with high-baseline pTau217. DISCUSSION: This study demonstrates the utility of QDRS for tracking pre-dementia AD-related decline.
