  1. ER estrogen receptor, PR progesterone receptor, NHG Nottingham histological grade, HER2 human epidermal growth factor receptor 2
  2. Age was defined as years at diagnosis. Positive ER and PR expression was considered as >10%. Chi square test, linear-by-linear test or Fisher’s exact test were used to test the significance between groups. Significant correlations (p < 0.05) are indicated by bold numbers
