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

Gastrointestinal colonization by the nosocomial pathogen vancomycin-resistant Enterococcus faecium (VREfm) can lead to bloodstream infections with high mortality rates. Shifts in VREfm lineages found within healthcare settings occur, but reasons underlying these changes are not understood. Here we sequenced 710 VREfm clinical isolates collected between 2017 and 2022 from a large tertiary care centre. Genomic analyses revealed a polyclonal VREfm population, although 46% of isolates formed genetically related clusters, suggesting a high transmission rate. Comparing these data to a global collection of 15,631 publicly available VREfm genomes collected between 2002 and 2022 identified replacement of the sequence type (ST) 17 VREfm lineage by emergent ST80 and ST117 lineages at the local and global level. Comparative genomic and functional analyses revealed that emergent lineages encoded bacteriocin T8, which conferred a competitive advantage over bacteriocin T8-negative strains in vitro and upon colonization of the mouse gut. Bacteriocin T8 carriage was also strongly associated with strain emergence in the global genome collection. These data suggest that bacteriocin T8-mediated competition may have contributed to VREfm lineage replacement.
