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-brain axis enables communication between the central nervous system and the gut, with certain microbial metabolites influencing neurodegeneration. Using genome-scale metabolic modeling, we designed and tested a synthetic microbial consortium with predicted capacity to produce GABA and other neurometabolites in a Drosophila melanogaster model of neurodegeneration of Parkinson's Disease (PD). The consortium (Levilactobacillus brevis, Lacticaseibacillus paracasei, Bacteroides thetaiotaomicron) produced GABA in bioreactors. Female PD flies receiving the consortium exhibited protection from locomotor impairment at 10 and 25 days upon consortium administration. Head metabolomics revealed partial restoration of PD-associated alterations in energy balance, amino acid and neurotransmitter metabolism, and disease-related biomarkers. Early administration increased microbiome diversity and Lactobacillus abundance. These findings suggest that rationally designed microbial consortia targeting neurometabolite production can modulate brain physiology and confer neuroprotection, supporting their potential for microbiome-based interventions in neurodegenerative disease.
