Prognostic significance of glutamate in medulloblastoma. a) Group-specific survival curves for all 78 patients with available data show WNT tumours have an excellent prognosis, whilst Group3 and SHH have poorer prognoses. b) Higher glutamate levels predict worse survival in 63 cases, following exclusion of those involved in the previous retrospective analysis which generated the hypothesis. p value derived using log-rank test. Life tables show the number at risk at each time point. c) Multi-variable analysis for whole group of 78 patients. LCA, large-cell/anaplastic histology.
