Microbial enterotype is linked to episodic and working memories via brain function in the parietal and occipital cortices.
Article in BMC biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundClassification of human gut microbiome into distinct enterotypes based on gut microbial community composition has provided an attractive framework for population stratification. While empirical evidence indicates that microbial enterotype is related to brain function and memory, the neural processes underlying this interaction remain to be further characterized.
resultsIn 510 healthy young adults, we used 16S rDNA amplicon sequencing to perform enterotyping, acquired resting-state functional MRI data to calculate brain functional measures, and assessed both episodic and working memories. Inter-enterotype differences in brain functional measures were examined, followed by performance of correlation and mediation analyses to disentangle the potential associations between enterotype, brain function, and memory. We found significant differences in multiple brain functional measures in the parietal and occipital cortices across Bacteroides, Prevotella, and Ruminococcaceae enterotypes. Moreover, these differential brain functional measures were correlated with both episodic and working memories, and further mediated the relationship between enterotype and memory.
conclusionsOur findings not only establish brain function as the mediating factor between enterotype and memory, but also hold translational potential for informing novel treatment for cognitive dysfunction via targeting the microbiota-gut-brain axis.
