Figure 1From: Evaluation of NDRG2 gene expression in primary papillary thyroid carcinoma and in metastases of this neoplasm to regional lymph nodes Box and whisker chart. The level of NDRG2 mRNA expression in macroscopically unchanged thyroid tissue and in PTC. The boxes represent means ± SEM. The results obtained with U-Mann-Whitney's test point to a statistically significant difference of NDRG2 expression in the investigated groups (p < 0.0001)Back to article page
