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

backgroundParkinson's disease (PD) is a progressive neurodegenerative disorder characterized by the accumulation of misfolded alpha-synuclein (α-Syn) and the subsequent loss of dopaminergic neurons. Identifying reliable and non-invasive biomarkers is crucial for accelerating early diagnosis and monitoring disease progression. To this aim, we longitudinally investigated α-Syn in salivary extracellular vesicles (SEVs) in PD patients and the correlation with clinical outcomes.

methodsSEVs were isolated from PD patients and healthy controls (HCs) saliva using differential ultracentrifugation followed by morphological and molecular characterization. The levels of both total (α-Syn

resultsWe found a significant increase in both α-Syn

conclusionsThese results establish for the first time that SEVs-associated α-Syn
