KIF2A and neoplasm: Multivariate Cox proportional hazards analysis also revealed that KIF2A was an independent prognostic marker associated with OS (HR: 0.366; 95% CI: 0.268–0.5; p < 0.001), as well as with tumor differentiation (HR: 1.229; 95% CI: 1.004–1.505; p = 0.046) and advanced tumor stage (HR: 1.324; 95% CI: 1.113–1.575; p = 0.002) (Table 3).
