Fig 5

Ki67 grade (A) and Ki67/CK grade (B) are negatively related with 5-DFS in all patients; Ki67 grade (C) has no statistical significance in lymph node-negative subgroup, but Ki67/CK grade (D) is negatively related with 5-DFS in lymph node-negative subgroup; Ki67 grade (E) and Ki67/CK grade (F) are negatively related with 5-DFS in node-positive subgroup. BC: breast cancer; 5-DFS: 5-year-disease free survival; CK: cytokeratin.
