Figure 3From: COX-2 expression in papillary thyroid carcinoma (PTC) in cytological material obtained by fine needle aspiration biopsy (FNAB) Box-and-whisker plots representing the COX-2 mRNA expression by quantitative RT-PCR in PTC and NTG groups. Results are calculated as ddCT values. Whiskers represent means ± SD (standard deviation) for particular groups. Boxes represent means ± SEM (standard error of mean). The results were statistically analyzed, using Student's t test.Back to article page
