Figure 7B and Supplementary Figure S6 show scatterplot data for the aforementioned tumors generated by a single algorithm. According to the TIDE algorithm, the degree of DDX21 expression in STAD is negatively correlated with the level of infiltration of cancer-associated fibroblasts (Figure 7B, cor = -0.178, p = 4.86e-04). Here, DDX21 is linked to cancer.
