IBrC—invasive breast cancer, HR—hazard ratio, BMI—body mass index, T1—<2 cm, T2—≥ 2 cm < 5 cm; other molecular subtypes include luminal B HER2−/+, basal-like, and non-luminal HER2+; significant values are denoted by bold p-values; underlined p-values represent closeness to statistical significance.
