As we expected, ZEB2 expression was significantly negatively correlated with tumor purity (r = −0.60, p value = 3.16e − 20) but positively associated with ESTIMATE score (r = 0.72, p value = 2.31e − 33), stromal score (r = 0.83, p value = 2.74e − 54), and immune score (r = 0.42, p value = 2.29e − 10). This evidence concerns the gene ZEB2 and neoplasm.
