SLC26A9 overexpression was associated with T stage (p < 0.05), lymph node metastasis (p < 0.05), distant metastasis (p < 0.01), TNM stage (p < 0.05), and Duke stage of CRC but was not correlated with age, sex or tumor size (Supplementary Figure 1A–H). Here, SLC26A9 is linked to colorectal carcinoma.
