STAT3 and neoplasm: On the contrary, although G-STAT3 activity had no correlation with purity (SCC = 0.004, p > 0.05, Fig. 3C), T-STAT3 seemed to be negatively correlated with tumor purity (SCC = −0.26, p = 5E-4, Fig. 3D), whereas E-STAT3 did not show a significant correlation (SCC = 0.08, P > 0.05, Fig. 3E).
