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

Acinetobacter baumannii is a Gram-negative pathogen responsible for hospital-acquired infections with high levels of antimicrobial resistance (AMR). The spread of multidrug-resistant A. baumannii strains has become a global concern. Spread of AMR in A. baumannii is primarily mediated by the acquisition of AMR genes through mobile genetic elements, such as plasmids. Thus, a comprehensive understanding of the role of different plasmid types in disseminating AMR genes is essential. Here, we analysed the distribution of plasmid types, sampling sources, geographic locations, and AMR genes carried on A. baumannii plasmids. A collection of 813 complete plasmid entries was collated and analysed. We previously devised an Acinetobacter Plasmid Typing (APT) scheme where rep types were defined using 95% nucleotide identity and updated the scheme in this study by adding 12 new rep/Rep types (90 types in total). The APT scheme now includes 178 unique Rep variants belonging to three families: R1, R3, and RP. R1-type plasmids were mainly associated with global clone 1 strains, while R3-type plasmids were highly diverse and carried a variety of AMR determinants including carbapenem, aminoglycoside and colistin resistance genes. Similarly, RP-type and rep-less plasmids were identified as important carriers of aminoglycoside and carbapenem resistance genes. This study provides a comprehensive overview of the distribution and characteristics of A. baumannii plasmids, shedding light on their role in the dissemination of AMR genes. The updated APT scheme and findings enhance our understanding of the molecular epidemiology of A. baumannii and provide valuable insights for surveillance and control strategies.
