Association between parity and luminal B-like, luminal human epidermal growth factor receptor-2 (HER2)-like, HER2-like and triple-negative breast cancer by age at diagnosis. A binary logistic regression model was fitted considering every molecular subtype as the response variable, while considering luminal A-like breast cancer as a reference category, and parity and age as explanatory continuous variables. Age was modeled non-linearly using cubic splines (5 knots). Blue lines represent probabilities for parous women, green lines probabilities for nulliparous women. a Probability of luminal B-like subtype by parity. b Probability of Luminal HER2-like subtype by parity. c Probability of HER2-like subtype by parity. d Probability of triple negative breast cancer (TNBC) subtype by parity
