215 Japanese and 493 Dutch employees in companies with periodic health screening, including 57 with past peptic ulcers (median 6 years since diagnosis) and 4 with current peptic ulcersDaily smoking at time of interviewOR (95% CI) adjusted for age, H. pylori infection, family history of peptic ulcers, and occupation, smokers vs. nonsmokers:
 Netherlands (men only)1.6 (0.5–4.9)
