Influence of IL1B polymorphism on CpG island hypermethylation in Helicobacter pylori-infected gastric cancer.
Article in Virchows Archiv : an international journal of pathology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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 infection can induce aberrant CpG island hypermethylation in gastric mucosal epithelial cells. Single nucleotide polymorphisms of proinflammatory cytokine genes encoding for interleukin 1B (IL1B), IL6, and IL8 have been demonstrated to be associated with an increased risk of gastric cancer. To identify the influence of host genetic factors in CpG island hypermethylation induced by H. pylori infection, we analyzed H. pylori-infected chronic gastritis (n = 111) and gastric cancer samples (n = 78) for the methylation status of eight genes previously shown to be hypermethylated in chronic gastritis and single nucleotide polymorphisms of IL1B, IL6, and IL8. The methylation levels were then compared between different genotypes. Gastric cancers from patients with the IL1B-511T/T allele showed significantly higher methylation levels in five genes as compared with gastric cancers from IL1B-511 C carriers (P < 0.05). An increased level of hypermethylation in association with the IL1B-511T/T allele was observed in chronic gastritis samples, but the association was not statistically significant. These findings suggest that the IL1B-511T/T allele is associated with enhanced hypermethylation of multiple CpG island loci, which might contribute to an increase in the risk for gastric cancer in individuals with H. pylori infection and IL1B-511T/T allele.
