^aIncluded are data from the 311 TCGA GBM patients who had all the following data available such as FBXO17 gene expression, IDH1 mutation, gender, age, survival time, and vital status. The numbers in parentheses denote the numbers of patients in the specified subgroups

^bwt, wide-type; mut, mutant

^cHR, hazard ratio; CI, confidence interval

^dBased on a multivariate Cox proportional hazards model, including all variables in the table

^eWald’s test, P values

^fThe median age of the common set is 60 years
