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.

Abstract

Crohn's disease is a chronic inflammatory condition of the gastrointestinal tract in which alterations to the bacterial community contribute to disease. Adherent-invasive Escherichia coli are associated with human Crohn's disease; however, their role in intestinal immunopathology is unclear because of the lack of an animal model compatible with chronic timescales. Here we establish chronic adherent-invasive Escherichia coli infection in streptomycin-treated conventional mice (CD1, DBA/2, C3H, 129e and C57BL/6), enabling the study of host response and immunopathology. Adherent-invasive Escherichia coli induces an active T-helper 17 response, heightened levels of proinflammatory cytokines and fibrotic growth factors, with transmural inflammation and fibrosis. Depletion of CD8+ T cells increases caecal bacterial load, pathology and intestinal fibrosis in C57BL/6 mice, suggesting a protective role. Our findings provide evidence that chronic adherent-invasive Escherichia coli infections result in immunopathology similar to that seen in Crohn's disease. With this model, research into the host and bacterial genetics associated with adherent-invasive Escherichia coli-induced disease becomes more widely accessible.
