Figure 7. The association between the CXC chemokines expression and immune infiltration level of multiple immune cells types estimated by all six algorithms in ad heatmap table across COAD and READ. The red indicates a statistically significant positive association (P ≤ 0.05, rho > 0), and the blue indicates a statistically significant negative association (P ≤ 0.05, rho < 0). White denotes a non-significant result (P > 0.05).
