Figure 1:

The prevalence of H. pylori infection as percent of total adult population (A), gastric cancer incidence presented as number per 100,000 (B) mapped with the most recent H. pylori prevalence data(5) and gastric cancer incidence rates from the WHO except where WHO did not have data, in which case data was supplemented from recent publications or presented as no data available (in gray) (101–103). As gastric cancer incidence is generally presented for male and females separately we took average of the two for the figures. The average for each country is presented. The locales of the three gastric cancer enigmas, the African Enigma, the Asian Enigma, and the Latin America High Altitude Enigma (C), highlighting the contrast of H. pylori infection incidence and gastric cancer prevalence.
