Table 2.

Odds ratios (ORs) and 95% confidence intervals (CIs) of PTPN11 rs2301756 polymorphism for H. pylori seropositivity.

Genotype, allele	n	H. pylori +	H. pylori + (%)	OR^a	95% CI	P value
G/G	1126	643	57.1	1	Reference	-
G/A	464	266	57.3	1.02	0.81–1.28	0.865
A/A	46	28	60.9	1.19	0.64–2.22	0.577

G	2716	1552	57.1	1	Reference	-
A	556	322	57.9	1.03	0.85–1.25	0.387

^aOR for each genotype was calculated by age and sex adjusted logistic regression model, and a crude OR was calculated for each allele.
