  • Data are presented as RR (95% confidence interval)

  • #: adjusted for age and cohort of origin

  • : males and females pooled, adjusted for age, sex, cohort of origin and smoking (six categories)

  • +: Chi‐squared test for interaction between birth cohort and level of education (females p=0.04; males p=0.25; pooled, adjusted p=0.05)
