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

backgroundPlasma phosphorylated tau (p-tau) biomarkers have improved the diagnosis of Alzheimer's disease (AD), but evidence in early-onset populations remains limited. We evaluated the diagnostic performance of plasma p-tau217 and p-tau181 levels in patients with early-onset AD (EOAD) and early-onset frontotemporal dementia (EOFTD).

methodsWe analyzed 185 patients (EOAD = 150, EOFTD = 35) aged ≤ 65 years from the LEAF study (2021-2023). Plasma p-tau217, p-tau181, neurofilament light (NfL), and glial fibrillary acidic protein (GFAP) levels were measured by immunoassays.

resultsBoth plasma p-tau217 (AUC = 0.831) and p-tau181 (AUC = 0.862) levels demonstrated high discriminative performance, with no significant difference between the two p-tau isoforms. P-tau levels were higher in patients with EOAD, whereas NfL levels were higher in EOFTD and were elevated in those with EOAD participants with severe hippocampal atrophy. Adding NfL, GFAP, and APOE ε4 status further improved the discriminative accuracy for differentiating EOAD from EOFTD.

conclusionsPlasma p-tau217 and p-tau181 are effective biomarkers for distinguishing biologically defined EOAD from EOFTD. Incorporating NfL, GFAP, and APOE ε4 status further enhances diagnostic accuracy.
