Like ER, the PR tumor subtype was frequently associated with HTN (PR = 1.13, 95% CI: 1.01–1.27, p = 0.036) and lobular carcinoma (PR = 1.35, 95% CI: 1.17–1.55, p < 0.001) and less likely to be associated with being postmenopausal (PR = 0.90, 95% CI: 0.80–1.00, p = 0.056). This evidence concerns the gene ESR1 and neoplasm.
