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

Attaching and effacing Escherichia coli (AEEC) strains are a genomically diverse group of diarrheagenic E. coli strains that are characterized by the presence of the locus of enterocyte effacement (LEE) genomic island, which encodes a type III secretion system that is essential to virulence. AEEC strains can be further classified as either enterohemorrhagic E. coli (EHEC), typical enteropathogenic E. coli (EPEC), or atypical EPEC, depending on the presence or absence of the Shiga toxin genes or bundle-forming pilus (BFP) genes. Recent AEEC genomic studies have focused on the diversity of the core genome, and less is known regarding the genetic diversity and relatedness of AEEC plasmids. Comparative genomic analyses in this study demonstrated genetic similarity among AEEC plasmid genes involved in plasmid replication conjugative transfer and maintenance, while the remainder of the plasmids had sequence variability. Investigation of the EPEC adherence factor (EAF) plasmids, which carry the BFP genes, demonstrated significant plasmid diversity even among isolates within the same phylogenomic lineage, suggesting that these EAF-like plasmids have undergone genetic modifications or have been lost and acquired multiple times. Global transcriptional analyses of the EPEC prototype isolate E2348/69 and two EAF plasmid mutants of this isolate demonstrated that the plasmid genes influence the expression of a number of chromosomal genes in addition to the LEE. This suggests that the genetic diversity of the EAF plasmids could contribute to differences in the global virulence regulons of EPEC isolates.
