Integrative multi-omics analysis reveals host-microbiome metabolic alterations and candidate biomarkers in Parkinson's disease.

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
Alterations in the gut microbiome have been increasingly implicated in Parkinson's disease (PD), but the associated metabolic changes remain incompletely understood. Here, we applied an integrative multi-omics approach combining shotgun metagenomic sequencing and untargeted LC-MS-based plasma metabolomics to investigate host-microbiome alterations in PD. Fecal and plasma samples were collected from 30 PD patients and 30 healthy spouse controls. Significant differences in microbial diversity and taxonomic composition were observed between the two groups. Taxonomic profiling revealed marked gut microbial dysbiosis in PD, including altered abundances of Phocea massiliensis, Bacteroides sp900766005, and Alistipes_A indistinctus. Metabolomic analysis identified 86 significantly altered plasma metabolites, including glycerophospholipids, indoleacetic acid, and kynurenic acid. Integrative pathway analysis suggested links between microbial functional alterations and host metabolic changes. Machine-learning analyses identified three biomarker panels that distinguished PD patients from controls in validation datasets, with the highest area under the curve (AUC) reaching 0.92. In silico molecular docking further suggested potential interactions between several metabolite biomarkers and alpha-2-macroglobulin (A2M) or the human B
