However, it was significantly associated with tumor stage (I + II vs. III + IV: HR = 3.676, 95%CI = 2.366–5.711, P = 7.05E–09), histopathological grade (G1 + 2 vs. G3 + 4: HR = 2.629, 95%CI = 1.655–4.176, P = 4.26E–05), and IFI16 expression level (low vs. high: HR = 1.043, 95%CI = 1.024–1.063, P = 1.07E–05). Here, IFI16 is linked to neoplasm.
