ADD3 and glioblastoma: Survival analysis of GBM with ADD3 copy number loss, 46 diploid vs. 157 deletion (Figure 2B) and MXI1 copy number loss, and 21 diploid vs. 69 deletion (Figure 2C) showed a significant correlation with an unfavorable outcome (log rank **p < 0.01), with a median survival of 12.95 months in ADD3-deleted tumors compared with 15.65 months in non-deleted (diploid) tumors (***p < 0.001) and median survival of 12.95 months in MXI1 deleted tumors compared with 28.47 months in non-deleted (diploid) tumors (***p < 0.001).
