Adjusted for age, gender, systolic blood pressure, diastolic blood pressure, body mass index, smoking habit, alcohol consumption, total cholesterol level, triglyceride level, high-density lipoprotein-C level, low-density lipoprotein-C level and fasting blood glucose level by logistic regression analysis. HP: Helicobacter pylori; AG: Atrophic gastritis; OR: Odds ratio; CI: Confidence interval.
