BCOR and medulloblastoma: The median overall survival time for CNS-BCOR ITD calculated by the Kaplan–Meier method was three years, and this prognosis was inferior to that of all major medulloblastoma (MB) groups except group 3 (Supplementary Figure S1, p value < 0.0001 vs. WNT activated MB, p value = 0.0038 vs. sonic-hedgehog-activated MB, p value = 0.0031 vs. group 4 MB, Log-rank test).
