With mutation or CNV: cases have mutant or CNV or mutant+CNV, confirmed through TCGA database. Without mutant and CNV: cases with neither mutant nor CNV, confirmed through TCGA database. Ambiguous variables (Nx, Mx, N/A, discrepancy, and Gx) were excluded from chi-square test or nonparametric test. value < 0.005.
