The capacity of gastrointestinal microbiota in kidney transplant recipients to ferment prebiotic starch.

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
backgroundDisruption of the gut microbiota in kidney transplant recipients has been linked to an increased risk of post-transplant infections and gastrointestinal symptoms, including diarrhoea. Dietary supplementation with resistant starch may mitigate these risks by promoting the growth of commensal gut bacteria that produce beneficial bioactive metabolites.
methodsFaecal microbiome profiles, gastrointestinal symptoms, and dietary habits were assessed in 13 individuals with kidney failure before and after transplantation, using 16S rRNA V4 amplicon sequencing, a modified Gastrointestinal Symptom Rating Scale (mGSRS) and a food frequency screener. The effect of resistant starch supplementation on the gut microbiota pre- and post-transplant was evaluated using a preclinical in vitro fermentation model with high amylose maize starch.
resultsGut microbiota diversity (based on richness and Shannon diversity index) declined significantly following kidney transplantation. This loss correlated with a higher frequency of gastrointestinal symptoms, including rectal pain. Significant shifts in microbiota composition were observed, including depletion of butyrate-producing Lachnospiraceae species, a change previously associated with post-transplant diarrhoea. These microbiota changes occurred independently of dietary patterns, which remained consistent throughout the study. Fermentation of high amylose maize starch in vitro by pre- or early post-transplant gut microbiota did not result in significant expansion of commensal bacterial populations.
conclusionsAlterations in the gut microbiota following kidney transplantation are associated with gastrointestinal symptoms. High amylose maize starch supplementation did not produce beneficial effects on the gut microbiota in preclinical model studies, either before or after transplantation.
