Nevertheless, it is noteworthy that, similar to male sex and old age, H. pylori (OR 1.22, 95% CI 1.08–1.38, P = 0.002), low-grade intraepithelial neoplasia (LGIN) (OR 1.79, 95% CI 1.21–2.66, P = 0.004), gastric fundus gland polyps (FGPs) (OR 1.44, 95% CI 1.11–1.87, P = 0.007), hyperplastic/inflammatory gastric polyps (GHP or GIP) (OR 1.50, 95% CI 1.06–2.12, P = 0.022), and atrophy/intestinal metaplasia (AG or IM) (OR 1.27, 95% CI 1.13–1.43, P < 0.001) were all risk factors for colorectal adenomatous polyps (AP). This evidence concerns the gene GIP and alkaline phosphatase measurement.
