Figure 3.

miR-23b expression levels in plasma samples from patients with CRC and healthy controls. Data are shown as the mean ± standard deviation of experiments. (A) miR-23b expression levels in plasma were significantly downregulated in CRC patients compared with healthy controls (P<0.001). (B) Receiver operating characteristic analysis showing the ability of the miR-23b level in plasma to discriminate between CRC patients and healthy controls. miR-23b, microRNA-23b; CRC, colorectal cancer; AUC, area under the curve; CI, confidence interval.
