Flow chart of patient identification and selection.
Stratified by age at breast cancer diagnosis (≤50 and >50 years), women with diabetes were 2:1 frequency-matched on year of birth and age at breast cancer diagnosis (both in 10-year categories) to women without diabetes, to select ~300 patients with tumor tissue available. ǂ Exact numbers <5 cannot be shown according to regulations of Statistics Denmark.
