S100A8 and gastric cancer: High-fruit consumers without evidence of H. pylori antibodies had the lowest odds for gastric cancer incidence (OR = 0.12, 95% CI: 0.06–0.25) when compared to low-fruit consumers who were infected with CagA-positive H. pylori. However, the inverse association with high-fruit consumption was lost in individuals infected with CagA positive H. pylori (OR = 0.82, 95% CI: 0.66–1.03).
