Breast cancer-free survival in relation to rs1800795 genotype. Kaplan-Meier estimates of breast cancer-free survival in relation to rs1800795 genotype. Since this is an ongoing cohort, there are fewer patients with longer follow-up times. a) Breast cancer-free survival among all patients with invasive tumours (Log Rank 1 df; P = 0.69). The adjusted HR was 1.11 (95% CI 0.69–1.77; P = 0.67). b) Breast cancer-free survival among patients with invasive ER-negative tumours (Log Rank 1 df; P = 0.014). The adjusted HR was 3.76 (95% CI 1.05–13.43; P = 0.041).
