This showed that a higher than median Patient Survival Score is related to longer overall survival of astrocytoma group patients (Log-rank test; χ2 = 42.630; df = 1; p < 0.001) (Figure 3) and is highly significant when combining the three chosen variables, rather than using each one individually (Figure 2A,E; data of individual IDH1 mutational status Kaplan–Meier analysis are not shown (Log-rank test; χ2 = 27.289; df = 1; p < 0.001)). The gene discussed is IDH1; the disease is astrocytoma (excluding glioblastoma).
