Association between H. pylori and demographic and gastritis severity variables: crude and adjusted prevalence ratios

Variables	Crude PR	95% CI	p-value
Age
< 30	1.00	Reference
30–39	1.13	0.70–1.82
≥ 40	1.06	0.65–1.72
Sex
Female	1.00	Reference
Male	1.12	0.74–1.70
Gastritis severity
Mild	1.00	Reference
Moderate	4.80	3.29–7.00	< 0.001
Severe	6.00	2.96–12.15	< 0.001

The variable “gastritis” was not included in this model due to collinearity with gastritis severity
