Further correlation analysis indicated that overexpression of CIRP was correlated with clinicopathological characteristics of patients with NSCLC including the T stage (P = 0.039) and an increased incidence of death (P = 0.002) as well as lymph node metastasis (P = 0.023) (Supplementary Table S1). This evidence concerns the gene CIRBP and metastatic malignant neoplasm in the lymph nodes.
