^aOnly first primary cancers are listed. Non-melanoma skin cancer (C44), chronic myeloproliferative disorders and myelodysplastic syndromes (D45-D47) were not counted as a cancer diagnosis; ^bNon-Hodgkin lymphoma; ^cCancers not in any mentioned group. IRR = calculated using Poisson model, adjusted for age, foreign status, and sex (when no stratified). People without diabetes were used as reference
