Furthermore, EGFR was negatively correlated with tumor purity in COAD (r = -0.0716) and READ (r = -0.18717, p = 0.026802), while MET exhibited no significant correlations with tumor purity in COAD (r = 0.01029, p = 0.836045) and READ (r = 0.017459, p = 0.83777). This evidence concerns the gene EGFR and neoplasm.
