Figure 2. The expression level of miR-199b in tissue samples and its relevance to prognosis.

A. Relative expression of miR-199b in 30 pairs of CRC tissues and CRM tissues measured by qRT-PCR. B. Relative miR-199b expression level in CRC tissues and CRN tissues (n=60). C. Kaplan-Meier survival curve for overall survival assay by miR-199b expression in 60 CRC patients. P value was obtained by a log-rank test. CRT: colorectal cancer tissues; CRN: colorectal normal tissues. *P<0.05, **P<0.01
