CDKN2B-AS1 and non-small cell lung carcinoma: To assess the correlation of lncRNA ANRIL expression with clinicopathologic features, according to the mean value of relative lncRNA ANRIL expression (3.6) in tumor tissues, the 87 NSCLC patients were classified into two groups: relative high-ANRIL group: ANRIL expression ratio ≥ mean; relative low-ANRIL group: ANRIL expression ratio < mean (Figure 1B).
