Helicobacter pylori Infection in Colombia: Phylogeny, Resistome, and Virulome.

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
Helicobacter pylori is a successful etiologic gastric agent that reaches a prevalence around 80% in Colombia. This bacterium is extremely diverse and has shown a phylogeographic pattern. The objective of this study was to perform an analysis of genomic epidemiology of H. pylori in Colombia. We enriched our set of 29 newly sequenced Colombian H. pylori genomes with additional data from public databases, reaching a total of 221 genomes in our dataset. Phylogenetic characterization was carried out using MLST and whole genome SNP analysis. We also performed a characterized the diversity of virulence factors and mutations associated with antimicrobial resistance. Phylogenetic analyzes showed two new Colombian H. pylori clades. Furthermore, many virulence genotype combinations were found, mutations associated with resistance were found for all the studied antibiotics, highlighting 14.4% of the genomes presented profiles associated with resistance to more than one family of antibiotics. Our analyzes described the genomics of Colombian H. pylori and verify the presence of a population group formed exclusively by Colombian isolates. We demonstrated the great diversity among the isolates and that the analysis by comparative genomics of H. pylori are valuable tools to assess the diversity, virulence, and resistance of H. pylori.
