MERTK and neoplasm: Comparing tumours with high versus low MERTK expression resulted in a multivariate hazard ratio (HR) of 1.61 for OS (CI0.95 = 1.1–2.36; significant coefficient for MERTK with P = 0.015; Wald test), 1.70 for DFS (CI0.95 = 1.24–2.33; significant coefficient for MERTK with P = 0.00094; Wald test) and 1.77 for RFS (CI0.95 = 1.26–2.48; significant coefficient for MERTK with P = 0.00087; Wald test), respectively.
