Genome-based identification of chromosomal regions specific for Salmonella spp.

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
Acquisition of genomic elements by horizontal gene transfer represents an important mechanism in the evolution of bacterial species. Pathogenicity islands are a subset of horizontally acquired elements present in various pathogens. These elements are frequently located adjacent to tRNA genes. We performed a comparative genome analysis of Salmonella enterica serovars Typhi and Typhimurium and Escherichia coli and scanned tRNA loci for the presence of species-specific, horizontally acquired genomic elements. A large number of species-specific elements were identified. Here, we describe the characteristics of four large chromosomal insertions at tRNA genes of Salmonella spp. The tRNA-associated elements harbor various genes previously identified as single virulence genes, indicating that these genes have been acquired with large chromosomal insertions. Southern blot analyses confirmed that the tRNA-associated elements are specific to Salmonella and also indicated a heterogeneous distribution within the salmonellae. Systematic scanning for insertions at tRNA genes thus represents a tool for the identification of novel pathogenicity islands.
