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

The Pseudomonas aeruginosa plasmid pKLC102 coexists as a plasmid and a genome island in clone C strains. Whereas the related plasmid pKLK106 reversibly recombines with P. aeruginosa clone K chromosomes at one of the two tRNA(Lys) genes, pKLC102 is incorporated into the tRNA(Lys) gene only close to the pilA locus. Targeting of the other tRNA(Lys) copy in the chromosome is blocked by a 23,395-bp mosaic of truncated PAO open reading frames, transposons, and pKLC102 homologs. Annotation and phylogenetic analysis of the large 103,532-bp pKLC102 sequence revealed that pKLC102 is a hybrid of plasmid and phage origin. The plasmid lineage conferred oriV and genes for replication, partitioning, and conjugation, including a pil cluster encoding type IV thin sex pili and an 8,524-bp chvB glucan synthetase gene that is known to be a major determinant for host tropism and virulence. The phage lineage conferred integrase, att, and a syntenic set of conserved hypothetical genes also observed in the tRNA(Gly)-associated genome islands of P. aeruginosa clone C chromosomes. In subgroup C isolates from patients with cystic fibrosis, pKLC102 was irreversibly fixed into the chromosome by the insertion of the large 23,061-bp class I transposon TNCP23, which is a composite of plasmid, integron, and IS6100 elements. Intramolecular transposition of a copy of IS6100 led to chromosomal inversions and disruption of plasmid synteny. The case of pKLC102 in P. aeruginosa clone C documents the intraclonal evolution of a genome island from a mobile ancestor via a reversibly integrated state to irreversible incorporation and dissipation in the chromosome.
