Table 4 Odds ratios value of Helicobacter pylori infection in different types of colorectal polyps and colorectal cancer from multivariable logistic regression, n (%)

	H. pylori negative	H. pylori positive	Odds ratio	95%CI	P value
Normal	2719 (73.35)	988 (26.65)	1
NAPs	503 (73.00)	186 (27.00)	1.03	0.86-1.24	0.72
LRAs	819 (71.28)	330 (28.72)	1.15	0.99-1.34	0.06
AAs	243 (66.21)	124 (33.79)	1.53	1.20-1.93	< 0.001
CRC	50 (67.57)	24 (32.43)	1.65	0.98-2.71	0.051

The showed multivariable associations. Sex and age were included in the model as covariates. Helicobacter pylori negative was the reference exposure (odds ratio = 1.00), and that “normal” colonoscopy findings were the reference outcome category. NAPs: Non-adenomatous polyps; LRAs: Low-risk adenomas; AAs: Advanced adenomas; CRC: Colorectal cancer; H. pylori: Helicobacter pylori; CI: Confidence interval.
