RFC2 and glioblastoma: Then Kaplan–Meier survival analysis demonstrated that high levels of RFC2 were significantly related to a poorer DSS in GBM, LGG, ACC, KICH, KIRC, LIHC, LUAD, and UVM (P = 0.005, P < 0.001, P < 0.001, P < 0.001, P = 0.029, P = 0.036, P = 0.007, and P < 0.001 respectively) (Fig. 5B–I).
