Figure 6. Correlation analysis of NAP1L1 and HDGF with overall survival of patients with glioma. (A) Representative immunohistochemistry images and IHC score of expression of NAP1L1 and HDGF in glioma tissues, respectively. Original magnification 400×. (B) Correlation analysis of NAP1L1 and HDGF with overall survival of patients with glioma. Prognostic significance assessed by Kaplan-Meier survival estimates. Comparison of the overall survival by HDGF (C), respectively. (D) Kaplan-Meier analysis of overall survival in patients with variable expression of NAP1L1 and HDGF. *P < 0.05, **P < 0.01, ***P < 0.001.
