IL33 and neoplasm: In the Abcam group, the expression of IL-33 was positively correlated with tumor stage (OR = 3.478, 95% CI = 2.237–5.407, p < 0.000) and negatively correlated with histological grade (OR = 0.571, 95% CI = 0.372–0.877), p = 0.011) but was not correlated with tumor size or lymphatic metastasis.
