Figure 4. Expression analysis of different RNAs in orbital venous malformation (OVM) and normal orbital vascular tissues. A, B, C: Volcano plot of differentially expressed mRNAs (A), circular RNAs (circRNAs) (B), and miRNAs (C) based on the thresholds of |log2 FC| ≥1 and p<0.05 in OVM and normal orbital vascular tissues. D, E, F: Hierarchical cluster analysis of differentially expressed mRNAs (D), circRNAs (E), and miRNAs (F) in OVM and normal orbital vascular tissues.
