Supplementary Table S1 from Complementary Value of Contralateral Parenchymal Enhancement on DCE-MRI to Prognostic Models and Molecular Assays in High-risk ER+/HER2− Breast Cancer

Competing risk analysis; Cox proportional hazards models are shown for overall survival, breastâ€cancer related death, and nonâ€breast cancer related death. For each model, pooled hazard ratios (HR) and 95% confidence intervals (CI) are shown. Contralateral parenchymal enhancement was inverse probability weighting†adjusted for age, tumor diameter on MRI, histological grade, axillary load, and systemic treatment. Pooled Pâ€values are shown for a trendâ€test between all three groups, intermediate CPE versus low CPE, and high CPE versus low CPE.
