ADAR and central nervous system cancer: Second, we use the median of ADAR1 expression levels in these 404 patients from their division into high‐risk and low‐risk groups, in the CGGA693 datebase (CGGA, the Chinese Glioma Genome Atlas; http://www.cgga.org.cn/) [19], and the survival curve showed that the high expression of ADAR was associated with poor prognosis in glioma (Figure S1B).
