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

backgroundFibrosis refers to abnormal deposition of extracellular matrix, which leads to organ dysfunction. Metabolic alterations, especially enhanced glycolysis and suppressed fatty acid oxidation, are recognized as an essential pathogenic process of fibrosis. Recently, several reports indicate that the changes in microbiota composition are associated with metabolic disorders, suggesting microbes may contribute to organ fibrosis by regulating metabolic processes.

methodsIn this study, microbial reannotation was carried out on the RNA-seq data of fibrotic organs. Then, the microbial composition differences among healthy and fibrotic organ samples were determined by alpha and beta diversity analysis. Common and specific microbial markers of fibrosis were also identified by LEfSe. After that, the correlation analysis of the characteristic microbegene- functional pathway was conducted to confirm the effects of microbes on host metabolism.

resultsThe results showed that the microbial composition significantly differed between healthy and diseased organs. Besides, the common characteristic microbes interacted closely with each other and contributed to fibrosis through symbiosis or inhibition. The largest proportion in fibrosis organs was Proteobacteria, which was the main source of pathogenic microbes.

conclusionFurther study found that the metabolic alteration driven by common and special characteristic microbes in fibrotic organs focused on the processes related to glycolysis and fatty acid metabolism.
