ATP2B1 and metastatic malignant neoplasm in the lymph nodes: The next multivariate Cox analysis revealed that ATP2B1-AS1 expression (95% CI = 2.136–20.120, P = 0.001), lymph node metastasis (95% CI = 1.055–11.205, P = 0.040) and TNM stage (95% CI = 1.056–5.624, P = 0.037) were independent prognostic factors of LUAD patients (Table 1).
