**Figure 4.** (**A**) Relationship between circRNA and miRNA. The yellow dots represent circRNAs and the green dots represent miRNAs. (**B**) miRNA-mRNA relationship pairs. (**C**) A Venn diagram, in which the purple circle represents 4386 predicted mRNAs, and the yellow circle represents 530 differentially expressed mRNAs in the experiment. Visualization of the ceRNA network. (**D**) The red triangle in the middle represents circRNA, the blue ellipse on the left represents miRNA, and the pink rectangle on the right represents mRNA. (**E**) Use the ggalluvial package for mapping, the longer the box, the more pairs of action relationships. (**F**) ROC curve for Unc13c, (**G**) ROC curve for Tbx20, and (**H**) ROC curve for St8sia2. The larger the area under the curve, the higher the AUC value and the better the prediction efficiency of disease.
