From: Long term trends of breast cancer incidence according to proliferation status
Incidence rates according to age, years of birth and proliferative marker status. Blue lines: women born before 1929. Red lines: Women born in 1929 or later. Dotted lines (red and blue) represent incidence rates of observed cases. Solid lines (red and blue) represent average incidence rates based on 50 imputed datasets with corresponding 95% CI. Fig. A-F shows breast cancer incidence according to A) Ki-67 < 15%, B) Ki-67 ≥ 15%, C) ≤3.6 mitoses/mm2, D) > 3.6 mitoses/mm2, E) < 7.7 mitoses/ mm2 and F) ≥7.7 mitoses/ mm2
