Figure 2:

Association of fibroids and endometriosis with hormone receptor subtypes among 4,419 breast cancer cases

Results from logistic regression model among breast cancer cases assessing the relationship between history of fibroids or endometriosis and breast cancer subtype (ER+ versus ER-, PR+ versus PR-, HER2+ versus HER2- and triple-negative vs. non-triple-negative). The referent group is no fibroids (or no endometriosis), regardless of surgical history. Age adjusted, partially adjusted, and fully adjusted models are included
