Figure 1 Cumulative gastric cancer incidences in H pylori–treated subjects compared with the expected gastric cancer incidence in the general population (A) for the whole cohort (n = 73,237) and (B) according to treatment outcomes (treatment success vs retreatment). “Expected” refers to the expected number of cases for individuals in the general population with similar age and sex of the entire cohort based on data from the Hong Kong Cancer Registry.

Figure 2 Cumulative incidences of gastric cancer in all H pylori–treated subjects (n = 73,237), after stratification by age at treatment, compared with the expected cumulative incidence in the matched general population. The curves were censored at 13 years. The expected number of gastric cancer cases was calculated using data from the Hong Kong Cancer Registry on individuals in the general population with similar age and sex.

Figure 3 Observed (red line) and expected (black line) incidence rates of gastric cancer in all H pylori–treated subjects (n = 73,237) and matched general population, according to age and follow-up durations of (A) less than 5 years, (B) 5–9 years, and (C) 10 years or longer.
