KIF14 and lung adenocarcinoma: Multivariate Cox proportional hazard regression analyses indicated that KIF14 expression (hazard ratio [HR] = 0.341, 95% confidence interval [CI] = 0.179–0.652; P = 0.0011) and disease stage (HR = 1.962, 95% CI = 1.311–2.936; P = 0.0010) were independent factors associated with the overall survival of lung adenocarcinoma patients (Table S2).
