  1. Percentages are calculated within each group, ie. IDC or ILC
  2. HR hormone receptor, HER2 human epithelial growth factor receptor 2, IDC invasive ductal cancer, ILC invasive lobular cancer, pT pathological tumor size
  3. *p-value for χ2 test, except when less than 5 observed in any cell then Fisher’s exact test
