With the analysis of the relationship between LINC00263 and clinical features of lung ADC patients (Table 1), We found that the expression level of LINC00263 was not significantly correlated with patient age (P = 0.3005, P = 0.5470), tobacco exposure (P = 0.7351), tumor stage (P = 0.1634, P = 0.1133), differentiation (P = 0.9547, P = 0.4165), or tumor involvement (P = 0.8501, P = 0.396) but was related to sex (P = 0.0481); LINC00263 was highly expressed in male tumor tissues (Fig. 2d). This evidence concerns the gene OLMALINC and neoplasm.
