Fig. 1

Neighbour-joining tree based on whole genome sequence alignment of all 173 strains from hpEurope-derived populations. Branches are shaded according to the population determined by fineSTRUCTURE analysis [17]. Labels reveal the patient disease background grouped into three categories: non-atrophic gastritis, progressive towards gastric cancer and gastric cancer. The scale bar represents a genetic distance of 0.02
