X-tile analyses of 3-year DFS was performed using patients’ data to determine the optimal cut-off value for TBIL, DBIL, and TBA. X-tile analyses of TBIL (a), DBIL (b), and TBA (c) levels in CRC patients. X-tile plots for patients are shown in the left panels; black circles highlight the optimal cutoff values, which are also shown in histograms (middle panels). Kaplan-Meier plots are presented in right panels, and in terms of DFS, the best cut-off values of TBIL, DBIL and TBA are 5.2 μmol/l, 13.1 μmol/l and 6.8 μmol/l, respectively
