As presented in Figure 2, decreased expression of RILPL2 is remarkably related to multiple factors, including age (P = 0.033, Figure 2A), tumor histological type (P < 0.001, Figure 2B), grade (P < 0.001, Figure 2C) and clinical stage (P < 0.001, Figure 2D). The gene discussed is RILPL2; the disease is neoplasm.
