Figure 1. Pathologic stage and lymph node metastases in LADC were correlated with MALAT1 mRNA expression levels. (A, B) From the TCGA database, correlations between lower MALAT1 mRNA expression and pathologic stage or lymph node metastasis of total, EGFR wild-type and EGFR mutant in LADC. A p-value <0.05 was regarded as statistically significant using Student’s t-test.
