From: A GWAS on Helicobacter pylori strains points to genetic variants associated with gastric cancer risk

Fig. 3

Prevalence of genes highlighted by GWAS in H. pylori genomes. a Prevalence of genes containing a GWAS hit with p value < 10−5 in three groups of isolates: non-atrophic gastritis isolates (red, n = 55 genomes), progressive toward cancer isolates (grey, n = 49) and gastric cancer isolates (black, n = 39), and defined as the ratio of number of isolates in each group harbouring the gene and the total number of isolates in each group. b Matrix of correlation of pairs of gene prevalence patterns in 143 H. pylori genomes. Red indicates that two genes have a high positive correlation of their patterns of presence and absence in all genomes examined and blue indicates a negative correlation. White indicates core genes that did not vary in prevalence in the dataset and for which correlations could not be calculated
