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

Recent research suggests that dietary prebiotics, probiotics, or healthy fecal-microbiota transplantation attenuate gut microbiota dysbiosis and ameliorate neurological disorders, in which gut-microbiota-derived γ-aminobutyric acid (GABA) has gained much attention as one of key mediators in the gut-brain axis. Although it is widely accepted that prebiotics and probiotics induce gut and brain GABA production via modulating gut microbiota, only evidence of probiotics has been solidly demonstrated while this evidence of prebiotics is scarce. Here, we demonstrated that prebiotic fructo-oligosaccharides and Aspergillus-derived enzymes elevated gut and brain GABA concentrations by modulating gut microbiota. Interestingly, we found that the prebiotic and enzymes increased a brain-specific dipeptide, homocarnosine. Gut GABA levels were found correlated with brain GABA/homocarnosine levels. Parabateroides, Akkermansia, Muribaculum, Hungatella, Marvinbryantia, Flavonifractor, and Incertae_sedis exhibited a positive correlation with gut GABA and brain GABA/homocarnosine levels, while Blautia, Unclassified_Lachnospiraceae, Colidextribacter, Acetatifactor, Roseburia, Unclassified_Oscillospiraceae, Romboutsia, and Eubacterium_coprostanoligenes exhibited a negative correlation with those levels.
