EN2 expression is negatively associated with glioma malignancy. a Stratified EN2 expression profiles of 75 glioma patients showing that EN2 was not correlated to the age, gender, status of onset, predominant location in side, and IDH1/2 mutation, but associated with predominant lobe and histological grade significantly. b Real-time PCR results showing that EN2 mRNA was decreased in gliomas compared to adjacent brain tissues (n = 75). c EN2 mRNA was decreased in high-grade gliomas (WHO III and IV, n = 17 and 33) in contrast to low-grade gliomas (WHO II, n = 25). d Kaplan–Meier survival analysis revealing that patients with higher EN2 expression carried a significantly better prognosis than the lower (n = 75). **p < 0.01 and ***p < 0.001
