Early population-level impact of Helicobacter pylori eradication on gastric cancer mortality in Japan: a counterfactual analysis of short-term divergence.
Japan's H. pylori eradication programs are already measurably reducing deaths from gastric cancer, one of the country's deadliest cancers.
Kowada A used counterfactual modeling to quantify the early population-level impact of Helicobacter pylori eradication programs on gastric cancer mortality in Japan, finding measurable short-term mortality divergence. The results provide policy-relevant evidence that H. pylori eradication interventions are already translating into detectable reductions in one of Japan's leading cancer killers.
