Figure 1 Prevalence of Helicobacter pylori infection by age group in Myanmar. Helicobacter pylori (H. pylori) infection was examined by 5 different methods including rapid urease test, culture, histology, immunohistochemistry, and serology. Subjects were considered to be H. pylori-negative when all 5 tests were negative, whereas H. pylori-positive status required at least one positive test result. Each bar shows the percentage of positive cases and the standard error.
