Epidemiology of dyspepsia and esophagogastroduodenoscopic findings in the era of Helicobacter pylori eradication

Figure 3 Multivariate logistic regression analysis of factors correlated with dyspepsia. This analysis revealed that the following factors were independently correlated with dyspepsia: Age < 60 years [odds ratio (OR) = 1.25; 95% confidence interval (CI): 1.15-1.35], female sex (OR = 1.81; 95%CI: 1.70-1.93), successful Helicobacter pylori eradication (OR = 1.14; 95%CI: 1.07-1.21), gastric ulcer (OR = 1.57; 95%CI: 1.01-2.44), duodenal ulcer (OR = 2.51; 95%CI: 1.20-5.26), reflux esophagitis (OR = 1.31; 95%CI: 1.16-1.49), and history of gastric surgery (OR = 1.57; 95%CI: 1.21-2.03). Conversely, no notable correlations were found for gastric or esophageal cancer. H. pylori: Helicobacter pylori; Los A: Los Angeles classification grade A reflux esophagitis; OR: Odds ratio.
