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

Gut dysbiosis contributes to Parkinson's disease (PD) pathogenesis. Gastrointestinal disturbances in PD patients, along with gut leakage and intestinal inflammation, take place long before motor disorders. However, it remains unknown what bacterial species in gut microbiomes play the key role in driving PD pathogenesis. Here we show that Helicobacter hepaticus (H. hepaticus), abundant in gut microbiota from rotenone-treated human α-Synuclein gene (SNCA) transgenic mice and PD patients, initiates α-Synuclein pathology and motor deficits in an AEP-dependent manner in SNCA mice. Chronic Dextran sodium sulfate (DSS) treatment, an inflammatory inducer in the gut, activates AEP (asparagine endopeptidase) that cleaves α-Synuclein N103 and triggers its aggregation, promoting inflammation in the gut and the brain and motor defects in SNCA mice. PD fecal microbiota transplant or live H. hepaticus administration into antibiotics cocktail (Abx)-pretreated SNCA mice induces α-Synuclein pathology, inflammation in the gut and brain, and motor dysfunctions, for which AEP is indispensable. Hence, Helicobacter hepaticus enriched in PD gut microbiomes may facilitate α-Synuclein pathologies and motor impairments via activating AEP.
