Supplementary Figure 8. Venn diagrams displaying the overlapping and unique miRNAs between overall and etiology-specific HCC. Only miR-424 was consistently down-regulated among all groups, and miR-6b was only significantly repressed in HBV-related HCC (A). Most etiology-related significant miRNAs were consistently observed in overall HCC, and only a few miRNAs were specifically identified in HCCs of individual etiology (B)
