Astrocytomas did not exhibit a statistically significant difference in IL13Rα2 expression from oligoastrocytomas and oligodendrogliomas (p=0.69, 2-way ANOVA with linear contrast to account for batch effects due to study) (Figure 1B), and no discernible differences were observed between the three histological subtypes (p=0.83, 2-way ANOVA to account for batch effects due to study). Here, IL13RA2 is linked to oligodendroglioma.
