Cost-Effectiveness Analysis of Helicobacter pylori Diagnostic Methods in Patients with Atrophic Gastritis

Figure 3

One-way sensitivity analysis. Sensitivity analysis using prevalence of clarithromycin- (CAM-) resistant Helicobacter pylori (H. pylori) showed that the order of effectiveness of seven diagnostic methods did not change between a CAM-resistant H. pylori prevalence of 0.1 and 0.7. The lines of histology and urea breath test were overlapped (a). In contrast, the cost of bacterial culture became equal to urine H. pylori antibody or rapid urease test or stool H. pylori antigen at between a CAM-resistant H. pylori prevalence of 0.3 and 0.58 (b).
