The landscape of immune infiltration in glioma. a The difference of immune infiltration between low- and high-grade glioma. b Correlation matrix of all 22 immune cell proportions in TCGA and CGGA datasets. c Heatmap of 22 immune cell proportions. The horizontal axis shows the clustering information of samples which were divided into two major clusters. d The distribution of same immune cells between low- and high-grade glioma. p-values show the significance of the distribution
