Figure 2From: 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 primary tumour and in metastases to regional lymph nodes. The results obtained with Spearman's rank correlation test did not demonstrate statistically significant differences between the level of expression in the investigated groups (p > 0.05).Back to article page
