Division of patients by the cut-off points produced by X-tile plot. X-tile plots for CEA. The produced log-rank χ2 value stratifies the pTxN0M0 GC patients into two groups by a cut-off value 30.02 ng/mL, showing a strong discriminatory capacity, with a χ2 value of 85.15 and a relative risk ratio of 1:2.15. CEA: Carcinoembryonic antigen.
