Expression and clinical significance of DKK4 protein expression in 239 EOC tissues. a Representative immunohistochemical expression of DKK4 protein in I-II and III-IV FIGO stage tissues. (100× magnification) (b) Kaplan–Meier curve showed the relationship between DKK4 expression and the Disease-free survival (DFS) of EOC patients. c The relationship between FIGO stage and the Disease-free survival (DFS) of EOC patients; *, p < 0.05
