Figure 5.

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