Intestinal biomarkers, microbiota composition, and genetic predisposition to inflammatory bowel disease as predictors of Parkinson's disease manifestation.
Article in Journal of Parkinson's disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
BackgroundParkinson's disease (PD) is often accompanied by gastrointestinal symptoms. While elevated inflammatory biomarkers have been reported in PD patients compared to controls, the role of intestinal dysmotility and inflammation in disease manifestation is not fully understood.ObjectiveThis study sought to determine if fecal biomarkers and genetic predisposition to intestinal inflammation could help identify PD subtypes for future targeted therapies.MethodsThe association of disease activity, assessed through United Parkinson's disease Rating Scale (UPDRS) and Non-Motor Symptoms Questionnaire (NMSQ), with constipation severity, fecal calprotectin and six short-chain fatty acid (SCFA) levels, polygenic risk scores (PRS) for inflammatory bowel disease (IBD) and PD, and microbiota diversity were investigated in 95 participants with established PD using regression analyses. Unsupervised k-means clustering was applied to stratify PD patients based on inflammatory biomarkers.ResultsHaving constipation was linked to worse mentation (UPDRSI, adj.
