Fig. 2From: Diagnostic performance of Midkine ratios in fine-needle aspirates for evaluation of Cytologically indeterminate thyroid nodulesScatter plots of (a) midkine (MK)/thyroglobulin (TG) ratio and (b) MK/free thyroxine (FT4) ratio in patients with benign thyroid nodules versus papillary thyroid carcinomas (PTCs) confirmed by histopathology. Both MK/TG and MK/FT4 ratios were significantly higher for PTCs than for benign thyroid nodules (P < 0.05)Back to article page
