A chi‐square test was applied for analysis and p < 0.05 was considered significant.

^*With mutation and/or CNV: Cases have mutant or CNV or mutant and CNV, confirmed through TCGA database. Without mutant nor CNV: Cases with neither mutant nor CNV, confirmed through TCGA database. Ambiguous variables (Nx, Mx, N/A and Gx) were excluded from chi‐square test or non‐parametric test.
