Table 3 Multivariate modelling of hazard ratios for tumour morphology features of the index cases.

From: Tumour morphology of early-onset breast cancers predicts breast cancer risk for first-degree relatives: the Australian Breast Cancer Family Registry

Feature Hazard Ratio (95% CI) P
Sclerosis - extensive 0.36 (0.20 to 0.65) 0.001
Acinar growth pattern 0.42 (0.22 to 0.78) 0.006
Glandular growth pattern 0.40 (0.25 to 0.65) <0.001
Extensive intraductal carcinoma 1.96 (1.28 to 3.00) 0.002
Circumscribed 1.85 (1.10 to 3.12) 0.02
