In the CGGA mRNA-array_301 dataset, univariate analysis showed that KDELR1 expression as well as age, the WHO grade, primary/recurrent/secondary type, histology, TCGA subtype, radiotherapy, chemotherapy, IDH mutation, and 1p/19q codeletion status were significantly associated with OS, and further multivariate analysis showed that KDELR1 expression and the chemotherapy status were independent prognostic predicators of OS in gliomas (Table 1). The gene discussed is KDELR1; the disease is glioma.
