Expression of miR-203 in adjacent non-cancerous liver and HCC tissues. Quantitative real-time PCR was performed to detect the expression of miR-203. a: Relative expression of miR-203 in adjacent non-cancerous liver and HCC tissues (dot plots with lines linking each pairs). b: The difference of relevant miR-203 expression between adjacent non-cancerous liver and HCC tissues. *** P  < 0.001. c: ROC curve of miR-203 expression to distinguish HCC from non-cancerous liver. The area under curve (AUC) of miR-203 was 0.85 (95 % CI: 0.796 ~ 0.904, P = 0.027) at a cut-off value of 1.99. Error bars represented standard deviation (SD). The statistical analysis was performed with Student’s t-test (a and b)
