Estimated dose response for incidence of diabetes in Hiroshima and Nagasaki, 1969 to 2015. Linear radiation dose response (black) and 95% confidence bounds (grey) at age at time of bombing (ATB) of individuals who were 10 (solid lines) and 30 (dashed lines) years old are shown for the incidence of diabetes. The estimated relative risks and 95% CIs at age ATB of those who were 10 (● ) and 30 (▲) years old are shown for 4 dose categories. Background was stratified by categories of age ATB (<15, 15-29, and ≥ 30) and calendar time (with breaks in 1982, 1986, 1999, and 2010). The model also adjusted for sex, Adult Health Study group, and smoking and alcohol drinking status.
