Brain-gut-microbiota axis: a review on the bidirectional regulatory mechanisms between gut microbiota and brain and their disease interactions.
Review in Frontiers in microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 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
Objective: To synthesize current evidence on the bidirectional regulatory mechanisms of the Brain-Gut-Microbiota Axis (BGMA), its perturbation by external factors, and its clinical implications for neurodegenerative, psychiatric, metabolic, and gastrointestinal disorders. Design: Narrative review integrating preclinical and clinical evidence. Data sources: PubMed/Medline, EMBASE, Cochrane Library searches (2000-2023) using keywords: "brain-gut-axis," "microbiota," "dysbiosis," "neuroinflammation," "SCFAs," "neurodegeneration," "psychobiotics." Results: Diet, stress, antibiotics, and environment significantly alter gut microbiota composition (e.g., reducing diversity, shifting Firmicutes/Bacteroidetes (F/B) ratio). Dysbiosis disrupts BGMA communication via: (1) Neural pathways (vagus nerve modulation); (2) Immune activation (cytokine release, neuroinflammation); (3) Microbial metabolites (SCFAs, tryptophan derivatives, TMAO). These disruptions are associated with Alzheimer's disease (reduced Conclusion: The BGMA is a critical mediator of systemic health. Dysbiosis contributes to disease pathogenesis through defined neural, immune, and metabolic pathways. Targeting the microbiota offers novel therapeutic strategies. Future research must prioritize translational studies validating microbial biomarkers and interventions in human cohorts.
