Figure 2. Box plot presentation of threshold cycle differences between malignant and benign biliary samples for target microRNAs (miR-16, miR-196a, miR-221). The ∆Ct values shown are presented after subtraction of the reference gene RNU6B threshold cycle numbers, and final results were depicted after subtraction from 40, therefore a higher number reflects higher value of expression. Results are shown as Box plots. Threshold cycle differences were significant in all cases, with the given p-values. Sample size is n=35.
