K-M curves also confirmed that risk score (P<0.0001, Figure 8A), CD8 T cells (P=0.0111, Figure 8B), activated memory CD4 T cells (P=0.0329, Figure 8C) and resting mast cells (P=0.0352, Figure 8D) have prognostic benefit for patients with PC. The gene discussed is CD8A; the disease is pachyonychia congenita.
