Interestingly, also when we restricted the analysis to the proneural subset of GBM, Kaplan-Meier survival curves, followed by log-rank test, showed that PATZ1 expression stratifies these patients (n = 24) in two statistically different subgroups where low PATZ1 has worse OS (HR = 3.191, 95% CI = 2.355-14.31, p = 0.001) and PFS (HR = 3.595, 95% CI = 2.785-19.06, p = 0.0006) (Figure 6B–6C). This evidence concerns the gene PATZ1 and glioblastoma.
