Fine-structure molecular typing of Irish Helicobacter pylori isolates and their genetic relatedness to strains from four different continents.
Article in Journal of clinical microbiology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
Genotyping of 74 Irish Helicobacter pylori isolates was performed at four different loci (vacA signal sequence and mid-region, insertion-deletion polymorphisms at the 3' end of the cag pathogenicity island, and cagA). The predominant vacA alleles and insertion-deletion motifs suggest an ancestral relationship between Irish isolates and either specific East Asian or Northern European strains. In addition, fluorescent amplified fragment length polymorphism-PCR genotyping and phylogenetic analysis of 32 representative Irish H. pylori isolates and 22 isolates from four different continents demonstrated that the Irish H. pylori isolates examined were weakly clonal and showed some association with both European and Asian isolates. These three genotyping techniques show that Irish H. pylori isolates have distinctive features that may have evolved in this insular European population.
