Notes:
(1) All the GBM cases in the above GEO datasets were included in our study except for 4 of 159 GBM cases in GSE16011 without survival information.
(2) The glioma samples but not GBM samples in GSE4290 (26 astrocytoma and 50 oligodendroglioma), GSE16011 (29 astrocytoma, 8 pilocytic astrocytoma, 52 oligodendroglioma and 28 mixed glioma) and GSE43378 (5 astrocytoma and 13 anaplastic oligodendroglioma) were not included in our study.
(3) In GSE90604, the data from 7 normal brain tissues were included while the data from 2 normal astrocyte cell lines were excluded in our study.
