Fig. 2: Correlation between IL18 expression level and clinical features.

A IL18 is highly expressed in gliomas. B Kaplan-Meier curve shows a significant correlation between high expression of IL18 and deteriorated OS. C qRT-PCR analysis shows high expression of IL18 in low-grade glioma tissue. D Univariate and multivariate Cox regression analyses show that high expression of IL18 is an independent prognostic factor for OS. E IHC detection of IL18 expression. F Correlation analysis between IL18 and clinical features (*p < 0.05, **p < 0.01, ***p < 0.001).
