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

Figure 5

Acceptability curves using Monte Carlo simulation analysis with 0.3 (a) and 0.45 (b) of clarithromycin- (CAM-) resistant Helicobacter pylori (H. pylori). Acceptability curve showed that serum H. pylori antibody or rapid urease test or urea breath test was an optimal diagnostic method depending on willingness to pay (WTP). Even if the prevalence of CAM-resistant H. pylori increased to 0.45, the probability that bacterial culture becomes an optimal method was low regardless of WTP.
