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.
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
Alpha synuclein (asyn) is expressed in neurons and is associated with the pathogenesis of synucleinopathies like Parkinson's Disease. Asyn aggregates are associated with phosphorylation at serine position 129 (pS129), which can be induced by environmental triggers, including viral infection, and the risk increases with aging. We show that brain tissue from West Nile Virus (WNV) infected patients exhibit increased expression of pS129 asyn in neurons of brain tissue. We found that WNV infection, Poly I:C treatment, and type 1 interferon (T1 IFN) treatment elicit the acute induction, followed by rapid degradation of pS129 asyn in olfactory pathways and primary cortical neurons. Induction of pS129 asyn was induced at these early time points independent of asyn aggregates. In IFN receptor knockout neurons, virus infection and Poly I:C stimulation do not induce pS129 asyn, implying that pS129 asyn is dependent on the type 1 interferon receptor. Our findings suggest that infections with DNA and RNA viruses and subsequent antiviral immunity can trigger the acute formation of pS129 asyn, and T1 IFN stimulation in neurons can trigger post-translational modifications in asyn. Further studies evaluating the interactions between pS129 asyn and interferon signaling may provide a common trigger for the formation of pathogenic asyn species.
