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

objectivesInflammatory bowel disease (IBD) is considered to result from interplay between host and intestinal microbiota. While IBD in adults has shown to be associated with marked changes in the intestinal microbiota, there are only a few studies in children, and particularly studies focusing on therapeutic responses are lacking. Hence, this prospective study addressed the intestinal microbiota in pediatric IBD especially related to the level of inflammation.

methodsIn total, 68 pediatric patients with IBD and 26 controls provided stool and blood samples in a tertiary care hospital and 32 received anti-tumor necrosis factor-α (anti-TNF-α). Blood inflammatory markers and fecal calprotectin levels were determined. The intestinal microbiota was characterized by phylogenetic microarray and qPCR analysis.

resultsThe microbiota varied along a gradient of increasing intestinal inflammation (indicated by calprotectin levels), which was associated with reduced microbial richness, abundance of butyrate producers, and relative abundance of Gram-positive bacteria (especially Clostridium clusters IV and XIVa). A significant association between microbiota composition and inflammation was indicated by a set of bacterial groups predicting the calprotectin levels (area under curve (AUC) of 0.85). During the induction of anti-TNF-α, the microbial diversity and similarity to the microbiota of controls increased in the responder group by week 6, but not in the non-responders (P<0.01; response related to calprotectin levels). The abundance of six groups of bacteria including those related to Eubacterium rectale and Bifidobacterium spp. predicted the response to anti-TNF-α medication.

conclusionsIntestinal microbiota represents a potential biomarker for correlating the level of inflammation and therapeutic responses to be further validated.
