Based on the univariate analysis by logistic regression, we determined that increased NCAPG2 expression was significantly correlated with WHO grade (G3 vs. G2), 1p/19q codeletion (non-codel vs. codel), primary therapy outcome (PR&CR vs. PD&SD), IDH mutation status (Mut vs. WT), and histological type (oligodendroglioma vs. oligoastrocytoma) (Table 2). Here, NCAPG2 is linked to oligodendroglioma.
