Prebiotic Administration to Chronic Kidney Disease Patients Modifies Their Fecal Microbiome and Host Metabolism.

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
OBJECTIVE(S): Prebiotics are believed to improve gut microbial dysbiosis and dysmetabolism in chronic kidney disease (CKD) patients. However, impact of prebiotics on gut microbial metagenome and dynamic changes in metabolome has not been clearly defined.
methodsWe conducted a nonrandomized, open-label, three-phase pilot trial to investigate the effect of daily oral prebiotic, oligofructose-enriched inulin (p-inulin), on stool functional metagenome and changes in plasma, urine, and stool metabolites in 13 CKD patients. The study comprised a pretreatment phase (8 weeks), p-inulin treatment phase (12 weeks), and post-treatment phase (8 weeks).
resultsDuring treatment phase, there was a significant increase in the abundance of Bifidobacterium adolescentis, Bifidobacterium longum, and Lachnospiraceae species. Microbial pathways related to carbohydrate degradation and amino acid biosynthesis were enriched during the treatment phase, but urea biosynthetic pathway was attenuated. In plasma, metabolic biosynthetic pathways for valine, leucine, and isoleucine were activated during the treatment phase. Microbial genes related to lipid metabolism were enriched during post-treatment. Abundance of several polar and nonpolar lipids were altered in plasma and stool samples during treatment and post-treatment phases. Pathway analysis for lipids indicated suppression of triglyceride biosynthesis in plasma and enhanced triglyceride degradation in stool during the treatment phase. Secondary bile acid levels in plasma, urine, and stool were significantly reduced during p-inulin consumption. Urine levels of indoxyl sulfate and p-cresol sulfate were reduced during treatment phase. CONCLUSION(S): P-inulin administration to CKD patients resulted in a distinct shift in toxin-generating proteolysis to amino acid biosynthesis and favorable changes in lipid metabolism.
