1 · What the graph read from it

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.

2 · The registry

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

Phosphorylated-tau 217 (pTau217) is currently the most promising blood-based biomarker for accurately detecting Alzheimer's disease (AD) pathology. However, interference from peripheral tau species in the kidneys or peripheral nerves can hinder diagnostic precision. Recently developed brain-derived pTau217 (BD-pTau217) assays emerge as highly specific tools for detecting AD-related pathological changes in the brain. In this study, we conducted a head-to-head comparison of the NULISAqpcr BD-pTau217 assay and Simoa ALZpath total p-Tau217 assay in two independent, amyloid-PET-characterized Chinese cohorts. Our results demonstrate a strong correlation between BD-pTau217 and total pTau217 (ρ = 0.89 to 0.90), with BD-pTau217 showing significantly reduced interference from kidney dysfunction, as evidenced by weaker associations with blood levels of urea (ρ
