Figure 5

Pearson's correlation of miRNA-mRNA pairs vs. significant confidences of their interactions discovered by SA-BNs. The x-axis shows the confidence of interactions, ranging from 0 (the least confident) to 1 (the most confident), while only the statistical significant scale remains (p-value < 0.05). The y-axis shows the sample correlations of identified miRNA-mRNA pairs. The red and blue points are miRNA-mRNA pairs which are correlated at the significant level (p-value < 0.05). It shows that the identified interactions are largely correlated, either negatively or positively, suggesting direct interactions and indirect interactions correspondingly.
