Gut ecosystem dysfunction in parkinson's disease: deciphering faecal metabolome-metagenome links for novel diagnostic panels.
Article in NPJ Parkinson's disease, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Gut ecosystem dysfunction is implicated in Parkinson's disease (PD), but integrative faecal metabolome-metagenome links are undefined. We explored these interactions in Chinese PD patients to develop diagnostic panels. Targeted faecal metabolomics (LC‒MS/MS) was performed on 132 PD and 113 healthy controls (HCs) and shotgun metagenomics was integrated for 39 PD/HC pairs. We identified 33 significantly altered faecal metabolites in PD (FDR-P < 0.05). A novel 12-metabolite panel could distinguish PD from HCs. Multi-omic integration revealed gut ecosystem dysfunction manifests via co-disruptions in microbial genes (e.g., amino acid metabolism genes) and metabolites. Critically, a combinatorial diagnostic panel integrating faecal metabolites and microbial gene markers achieved exceptional PD detection (AUC = 0.961, 95% CI = 0.923-0.998). This study deciphers metabolome-metagenome links driving gut dysfunction in PD, identifying amino acid metabolism as a core perturbed pathway. The novel diagnostic panels provide mechanistic insights and clinical tools for PD precision diagnosis.
