1 · What the graph read from it

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.

2 · The registry

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

The gut microbiota plays a crucial role in the communication between the gut, liver, and brain through the production of short chain fatty acids (SCFAs). SCFAs serve as key mediators in the Gut-Liver-Brain Axis, influencing various physiological processes and contributing to overall health. SCFAs are produced by bacterial fermentation of dietary fiber in the gut, and they exert systemic effects by signaling through various pathways. In the Gut-Liver axis, SCFAs regulate liver metabolism through peroxisome proliferator-activated receptor-γ (PPAR-γ), AMP-activated protein kinase (AMPK) and other pathways, promotes fat oxidation, modulate inflammation through mTOR pathway, and impact metabolic health. In the Gut-Brain axis, SCFAs influence brain function, behavior, and may have implications for neurological disorders, in which G-protein coupled receptors (GPCRs) play an essential role, along with other pathways such as hypothalamic-pituitary-adrenal (HPA) pathway. Understanding the mechanisms by which SCFAs mediate communication between the gut, liver, and brain is crucial for elucidating the complex interplay of the Gut-Liver-Brain Axis. This review aims to provide insight into the role of gut microbiota-derived SCFAs as mediators of the Gut-Liver-Brain Axis and their potential therapeutic implications. Further research in this area will be instrumental in developing novel strategies to target the Gut-Liver-Brain Axis for the prevention and treatment of various health conditions.
