Genetic variation and historical breeding patterns in common bean (Phaseolus vulgaris L.) affect fermentation patterns by the human gut microbiome.

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
Common beans, which contain diverse bioactive molecules, have not been systematically studied for their variation in how they affect the human gut microbiome. We measured taxonomic shifts and metabolite production of three human gut microbiomes cultured with 299 common bean cultivars under conditions that mimic the nutrient availability of the human colon. Common bean population structure (landrace and market class) had significant effects on microbiota diversity, composition, and metabolite production. Genome-wide association analysis identified seven multiple effect loci (MEL) where genetic variation in the common bean genome affected the microbiome. One MEL on chromosome Pv05 had impacts on the abundance of several Lachnospiraceae and Ruminococcaceae. Molecular complementation experiments suggested that variation in the biosynthesis of saponins at this MEL was the mechanism driving the variability in microbiota composition and function. This study provides innovative understanding of how genetics of common beans affects the human gut microbiome and potentially human health.
