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

The identification of biomarkers predicting the burden of brain alpha-synuclein (α-syn) pathology in vivo represents a research priority in Lewy body disease (LBD). Recently, some kinetic parameters of seed amplification assays (SAAs) for α-syn showed associations with measures of clinical progression. However, preanalytical and analytical factors significantly affect these parameters, reducing reproducibility. The Endpoint Dilution (ED) SAA Real-time Quaking-induced Conversion (RT-QuIC) is emerging as an alternative, more accurate tool for seed quantification. Still, the approach needs validation in large patient cohorts. We applied the ED RT-QuIC to postmortem ventricular cerebrospinal fluid (CSF) samples from 357 brain donors, including 168 who showed LBD at neuropathologic examination. We estimated the seeding dose, yielding positive responses in 50% of replicate reactions (SD50), using the midSIN algorithm and correlated these values with postmortem synuclein pathology burden and clinical severity measures. LBD was staged through the Unified Staging System for Lewy Body Disorders and the Lewy pathology consensus criteria. The SD50 values (expressed in log
