E: Crude incidence and excess relative risk of stomach cancer (1958-1987)
•
The crude incidence in the control, low-dose and high-dose groups (all ages) showed a dose response relationship of 15.2, 16.3 and 21.3 per 104person-years, respectively (P<0.001).
•
The risk was higher in people who were young at the time of bombing than in those who were old at the time of bombing.
