Kaplan-Meier analysis of overall survival (OS) and disease-free survival (DFS) curves of patients with osteosarcoma based on periostin expression as strongly positive, weakly positive or negative. (A) OS curve of patients with osteosarcoma based on periostin expression; (B) DFS curve of patients with osteosarcoma based on periostin expression. The osteosarcoma patients with periostin-positive expression showed significantly poorer OS and DFS rates than those with periostin-negative expression. The survival of patients in the strongly positive periostin expression was poorest.
