We performed Kaplan-Meier survival analysis and found that the expression levels of LDLRAD3 (p = 0.032), LMNB2 (p = 0.042), NMB (p = 0.005), SNTB1 (p = 0.038), SOX4 (p = 0.022), TRAF5 (p = 0.047), SNHG16 (p = 0.049) and has-mir-1271-5p (p = 0.032) could influence the prognosis in elderly patients with CRC (Fig. 2B–H). This evidence concerns the gene SNTB1 and colorectal carcinoma.
