Figure 3. Box plot of the relative expression levels of dysregulated miRNAs in the validation cohort (n = 160).

The y axis indicates log₁₀ 2^−△△Ct relative expression of miRNA. All 5 dysregulated miRNAs exhibited similar expression patterns in the training phase (miR-15b, p = 0.0071; miR-17, p = 0.0005; miR-21, p = 0.0011; miR-26b, p < 0.0001; miR-145, p = 0.0047).
