1 · What the graph read from it

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.

2 · The registry

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

backgroundCurrent knowledge suggests that proton pump inhibitors (PPIs) are associated with an increased risk of hepatic encephalopathy (HE) and spontaneous bacterial peritonitis (SBP). These conditions and PPI use are related to gut microbiota. The aim of this study is to research the changes in gut microbiota caused by PPI in patients with chronic liver disease.

methodsFrom 198 Japanese patients, 31 patients in the PPI and non-PPI groups were matched using propensity score matching (PSM) based on age, sex, and Child-Turcotte-Pugh class. We investigated the gut microbial composition of stool samples using the Illumina MiSeq sequencing platform and compared them using linear discriminant analysis effect size and phylogenetic investigation of communities by reconstruction of unobserved states.

resultsBefore PSM, Child-Turcotte-Pugh score (p = 0.038), ascites (p = 0.049), encephalopathy (p = 0.023), and esophageal varices (p < 0.01) were significantly higher in the PPI group than in the non-PPI group. After PSM, six genera, consisting of Lactobacillus, Streptococcus, Selenomonas, Veillonella, Campylobacter, and Haemophilus were enriched in the PPI group. Eggerthella, Paraprevotella, Turicibacter, Dorea, Anaerotruncus, and Ruminococcus were less abundant in the PPI group. We identified five types of level 3 KEGG pathways predicted to be significantly different.

conclusionsPart of microbial changes caused by PPI use was common to the changes by progression of liver cirrhosis. Increases in oral bacterial flora and decreases in autochthonous flora may produce the intestinal environment which tends to make the risk factor for HE or SBP.
