Breast cancer-free survival in different treatment groups in relation to rs1800795 genotype. a) Kaplan-Meier estimates of breast cancer-free survival in relation to rs1800795 genotype among chemotherapy-treated patients (Log Rank 1 df; P = 0.030). The adjusted HR was 3.42 (95% CI 1.01–11.54; P = 0.048). Since this is an ongoing cohort, there are fewer patients with longer follow-up times. b) Kaplan-Meier estimates of breast cancer-free survival in relation to rs1800795 genotype among radiotherapy-treated patients (Log Rank 3 df; P < 0.0001). The adjusted HR was 7.17 (95% CI 1.16–32.28; P = 0.010). Since this is an ongoing cohort, there are fewer patients with longer follow-up times.
