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

backgroundThe remission of Crohn's disease (CD) can be accomplished by faecal microbiota transplantation (FMT). However, this procedure has a low success rate, which could be attributed to mis-communication between recipient intestinal mucosa and donor microbiota.

methodsHere we used a human explant tissue model and an in vivo mouse model to examine changes in recipient intestinal mucosa upon contact with a faecal suspension (FS) obtained from a healthy donor. CD patients provided resected inflamed and non-inflamed mucosal tissues, whereas control colonic mucosa samples were collected from colorectal cancer patients. For the models, mucosal microbiome composition and tissue response were evaluated.

findingsWe show that cytokine release and tissue damage were significantly greater in inflamed compared to non-inflamed CD tissues. Moreover, mucosal samples harbouring an initial low microbial load presented a shift in composition towards that of the FS, an increase in the relative count of Faecalibacterium prausnitzii, and a higher secretion of anti-inflammatory cytokine IL-10 compared to those with a high microbial load.

interpretationOur results indicate that FMT during active inflammatory disease can compromise treatment outcome. We recommend the stratification of FMT recipients on the basis of tissue microbial load as a strategy to ensure successful colonization.

fundingThis study was supported by grants from the Instituto de Salud Carlos III/FEDER (PI17/00614), the European Commission: (INCOMED-267128) and PERIS (SLT002/16). K.M. is a postdoctoral fellow and S.V. a senior clinical investigator of the Fund for Scientific Research Flanders, Belgium (FWO-Vlaanderen).
