Analysis of gastric mucosa associated microbiota in functional dyspepsia using 16S rRNA gene next-generation sequencing.

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
Gastric disorders have been associated with changes in the abundance and composition of microbiota, which typically coexist in symbiosis within the stomach. There is a scarcity of data regarding the presence of gastric mucosa-associated dysbiosis in functional dyspepsia. The present study aimed to characterize the taxonomy and diversities of the microbiota in the gastric mucosa of patients with functional dyspepsia. The study was conducted on a total of 50 paired antral and body gastric biopsies collected from the dyspepsia group (n = 15) and control group (n = 10). Microbial DNA was extracted from all gastric biopsies, followed by 16 S rRNA gene next-generation sequencing (NGS) using the Miseq Illumina platform. Firmicutes, Proteobacteria, and Bacteroides were the most predominant phyla in both groups, with a significant overrepresentation of Proteobacteria in the dyspepsia group (p value = 0.004). The genera Streptococcus, Prevotella, and Helicobacter were the most prevalent in both groups. The species of H. pylori and Prevotella melaninogenica were significantly more abundant in the dyspepsia group. The species of The LEfSe analysis revealed that E. coli, Helicobacter, Pseudomonas, Bifidobacteria, and Enterobacteriaceae were the most highly abundant and discriminating taxa in the gastric biopsies of the dyspepsia group compared to the control group. The microbial alpha diversity was significantly higher among gastric biopsies of dyspepsia than controls (P = 0.031). The beta diversity showed microbial dissimilarity between samples of dyspepsia and the control group. The 16 S rRNA gene NGS used in the present study demonstrated significant alteration in composition and diversities of gastric mucosa-associated microbiota among cases of functional dyspepsia compared to the controls. It is advisable to utilize advanced innovative technologies to gain a deeper understanding of the underlying pathophysiology of disrupted microbiota in gastric disorders.
