Figure 2. Kaplan–Meier curves of OS and DFS in different expression levels of HIPK family. (A) Lower HIPK2 and HIPK3 expressers had shorter OS than the higher expressers, HIPK1 and HIPK4 expression had no difference in OS. (B) Lower HIPK2 and HIPK3 expressers had shorter DFS than the higher expressers, HIPK1 and HIPK4 expression had no difference in DFS. OS, overall survival; DFS, disease–free survival; HIPK, Homeodomain interacting protein kinases.
