Genomic O island 122, locus for enterocyte effacement, and the evolution of virulent verocytotoxin-producing Escherichia coli.

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.
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
The locus of enterocyte effacement (LEE) and genomic O island 122 (OI-122) are pathogenicity islands in verocytotoxin-producing Escherichia coli (VTEC) serotypes that are associated with outbreaks and serious disease. Composed of three modules, OI-122 may occur as "complete" (with all three modules) or "incomplete" (with one or two modules) in different strains. OI-122 encodes two non-LEE effector (Nle) molecules that are secreted by the LEE type III secretion system, and LEE and OI-122 are cointegrated in some VTEC strains. Thus, they are functionally linked, but little is known about the patterns of acquisition of these codependent islands. To examine this, we conducted a population genetics analysis, using multilocus sequence typing (MLST), with 72 VTEC strains (classified into seropathotypes A to E) and superimposed on the results the LEE and OI-122 contents of these organisms. The wide distribution of LEE and OI-122 modules among MLST clonal groups corroborates the hypothesis that there has been lateral transfer of both pathogenicity islands. Sequence analysis of a pagC-like gene in OI-122 module 1 also revealed two nonsynonymous single-nucleotide polymorphisms that could help discriminate a subset of seropathotype C strains and determine the presence of the LEE. A nonsense mutation was found in this gene in five less virulent strains, consistent with a decaying or inactive gene. The modular nature of OI-122 could be explained by the acquisition of modules by lateral transfer, either singly or as a group, and by degeneration of genes within modules. Correlations between clonal group, seropathotype, and LEE and OI-122 content provide insight into the role of genomic islands in VTEC evolution.
