L–R proliferation rate comparison by KI67 and mitotic index. A Comparison of L–R KI67 expression in 1060 primary breast tumors from TCGA. L expression is subtle but significantly increased (10.76 ± 0.05259 N = 571) as compared to R (10.52 ± 0.05836 N = 524) (Unpaired T-test, p = 0.002). B Proportion of 95 L–R IDC breast tumors from local female patients with high and low mitotic count (Fisher’s exact Test, p = 0.002)
