EFNA3 and hepatocellular carcinoma: The results indicated that EFNA3 was notably positively associated with tumor purity (Rho = 0.137, p = 1.1e-02), B cells (Rho = 0.226, p = 2.26e-05), CD4+ T cells (Rho = 0.191, p = 3.55e-04), neutrophil cells (Rho = 0.202, p = 1.55e-04), macrophage cells (Rho = 0.219, p = 4.11e-05), and dendritic cells (Rho = 0.304, p = 8.24e-09) in HCC (Figure 7A).
