We further distinguished CGGA_325 and CGGA_693 datasets by tumor grade, and the correlation analysis found that TP73 expression was significantly correlated with the status of 1p/19q codeletion regardless of tumor grade (p < 0.05) (Table S2), except for CGGA_693 grade II subgroup (p = 0.8715). This evidence concerns the gene TP73 and neoplasm.
