Receiver operator characteristic curves of miR-17-5p and miR-21 for discriminating non-PC from PC. Receiver operating characteristic areas under the curve of miR-17-5p and miR-21 were 0.887 (95% confidence interval (CI) = 0.796 to 0.978) and 0.897 (95% CI = 0.803 to 0.991), respectively. At the cutoff values of 6.826 for miR-17-5p and 7.693 for miR-21, specificities and sensitivities were 72.7% and 92.6% for miR-17-5p and 95.5% and 81.5% for miR-21, respectively.
