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

Figure 1 Prevalence rates of upper gastrointestinal symptoms. A: Prevalence of upper gastrointestinal symptoms, including heartburn, upper abdominal pain and bloating, and dyspepsia by 10-year age groups and in the overall population. The prevalence of upper abdominal pain declines after the age of 60 years, while bloating gradually decreases with advancing age; B: Comparison of dyspepsia prevalence between participants younger than 60 years and those aged ≥ 60 years. Dyspepsia is statistically significantly more prevalent in participants aged < 60 years than in those aged ≥ 60 years (Fisher’s exact test: ^aP < 0.001).
