LDLRAD4 and colorectal carcinoma: Moreover, as shown in Table 1 and Fig. 1c, we found that higher expression of lncRNA LDLRAD4-AS1 was significantly correlated with large tumor size (p = 0.045), involvement in lymph node metastasis (p = 0.014), advanced TNM stage (p = 0.014), and vascular invasion (p = 0.023) in CRC patients.
