Level of miR-92a and miR-30b in HBV+ B-NHL, HCV+ B-NHL, Ctrl B-NHL and RLN groups. Box-plot representation of the level of miR-92a (A) and miR-30b (B) in HBV+ B-NHL, HCV+ B-NHL, Ctrl B-NHL and RLN sample groups. HBV+ B-NHL: B-NHLs from HBV positive patients; HCV+ B-NHL: B-NHLs from HCV positive patients; Ctrl B-NHL: control B-NHLs from patients negative for both HBV and HCV. The level is reported as 2-Ct values. p values < 0.1 are reported, and those < 0.05 are shown in bold. C and D: summary of fold-change (vs. reference Ctrl B-NHL and RLN, respectively) and p-value (Mann-Withney test). Fold-change was calculated as ratio between median level of each group vs. median level of the reference group.
