a, b Kaplan–Meyer overall survival probability curves for cases from DKFZ RNA-seq dataset with high and low expression of PDIA6 in entire (a) and relapsed (b) Group 3/4 MB cohorts disclosed unfavorable OS for tumors with elevated gene expression (log rank; p < 0.01). c, d Kaplan–Meyer survival probability curves for cases with high and low expression of SNORD115-23 in entire (c) and relapsed (d) Group 3/4 MB cohorts disclosed unfavorable OS for tumors with low levels of gene expression (log rank; p < 0.01). For relapsed cohort (b,d) survival time was calculated from re-operation to the last event
