Kaplan–Meier analysis with the log-rank test based on 270 patients with colon cancer indicated that the expression level of CDKN1B mRNA had no significant effect on OS (p > 0.05) (Supplementary Figure S4C) or DFS (p > 0.05) (Supplementary Figure S4D). This evidence concerns the gene CDKN1B and colonic neoplasm.
