Figure 3From: 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 dependence of the level of NDRG2 mRNA expression on the tumour grade (pT, TNM scale) in two investigated PTC groups: pT1 (n = 10) and pT2-pT4 (n = 4). The boxes represent means ± SEM. The results were obtained with Spearman's rank correlation test (p > 0.05).Back to article page
