LCN1 and glioblastoma: Post  hoc tests with Bonferroni correction indicated that LCN1 was significantly overrepresented in LGG (Pearson residuals = 3.29; P = 0.0059) and IDH-mutated/1p19q-codeleted tumours (residuals = 5.65; P < 1e-6), but underrepresented in GBM (residuals = −3.29; P = 0.0059) and IDH-wt tumours (residuals = −4.05; P = 0.00046).
