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

introductionPlasma biomarkers offer promise for improving the diagnosis of Alzheimer's disease (AD) and differentiating AD and other neurodegenerative disorders (NDs) like frontotemporal dementia (FTD) from primary psychiatric disorders (PPDs), particularly in younger patients.

methodsIn this prospective study, we investigated plasma phosphorylated tau 217 (p-tau217), neurofilament light chain (NfL), and glial fibrillary acidic protein (GFAP) in 341 unselected participants from a neuropsychiatry memory clinic, including AD (n = 40), behavioral variant FTD (bvFTD) (n = 15), PPD (n = 69), other NDs, and controls.

resultsPlasma p-tau217 showed strong diagnostic performance for distinguishing AD from bvFTD (96% accuracy) and PPD (93% accuracy). NfL best distinguished all NDs from PPD, while GFAP did not bring additional value. Biomarker profiles using predefined cut-offs and age-adjusted z-scores further clarified group differences. DISCUSSION: Plasma p-tau217 and NfL have strong diagnostic utility in real-world, diagnostically complex cohorts. These findings support implementation of scalable blood-based biomarkers to improve early and accurate diagnosis in memory clinical settings. HIGHLIGHTS: Plasma p-tau217 was significantly elevated in AD compared to other disorders. P-tau217 distinguished AD from bvFTD with high accuracy. P-tau217 distinguished AD from PPDs with high accuracy. NfL/p-tau217 ratio and GFAP added limited diagnostic value compared to p-tau217 and NfL. Findings support blood biomarkers in younger, real-world clinical cohorts.
