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

Adherent-invasive Escherichia coli (AIEC) pathogroup isolates are a group of isolates from the intestinal mucosa of Crohn's disease patients that can invade intestinal epithelial cells (IECs) or macrophages and survive and/or replicate within. We have identified the ibeA gene in the genome of AIEC strain NRG857c and report the contribution of IbeA to the interaction of AIEC with IECs and macrophages and colonization of the mouse intestine. An ibeA deletion mutant strain (NRG857cΔibeA) was constructed, and the in vitro effect on AIEC adhesion and invasion of nonpolarized and polarized Caco-2 cells, the adhesion and transcytosis of M-like cells, the intracellular survival in THP-1 macrophages, and the contribution to intestinal colonization of the CD-1 murine model of infection were evaluated. A significant reduction in invasion was observed with the ibeA mutant in Caco-2 and M-like cells, whereas adhesion was not affected. Complementation of the mutant reestablished Caco-2 invasive phenotype to wild-type levels. Reduction in invasion did not significantly affect transcytosis through M-like cells at early time points. The absence of ibeA significantly affected AIEC intramacrophage survival up to 24 h postinfection. No significant changes associated with IbeA were found in AIEC colonization across the murine gastrointestinal tract, but a slight reduction of gamma interferon was observed in the ceca of mice infected with the ibeA mutant. In addition, a decrease in the pathology scores was observed in the ilea and ceca of mice infected with the ibeA mutant. Our data support the function of IbeA in the AIEC invasion process, macrophage survival, and inflammatory response in the murine intestine.
