THADA and undifferentiated carcinoma: By contrast, a significant correlation was found constraining the analysis to the follicular and papillary carcinoma samples (p = 0.0497, r = 0.456, n = 19), an even stronger correlation between the expression of THADA and NIS was found in normal and all malignant samples (p = 0.0021, r = 0.540, n = 30), and in normal tissue and anaplastic carcinomas (p = 0.0128, r = 0.718, n = 11)
