POSTN and pancreatic neoplasm: We next analyzed the Kaplan–Meier plotter database, which revealed that high expression of POSTN was associated with shorter overall (OS) (HR = 1.69, 95% CI: 1.03–2.78, p = .038) as well as relapse‐free survival (RFS) (HR = 4.72, 95% CI: 1.37–16.18, p = .0071) in pancreatic cancer patients (Figure 2B).
