Level of miR-223, miR-92a, miR-29a and miR-29b in HCV+ NMZL, Ctrl NMZL and RLN groups. A: box-plot representation of the level of miR-223, miR-92a, miR-29a and miR-29b in HCV+ NMZL, Ctrl NMZL and RLN sample groups. HCV+ NMZL: NMZLs from HCV positive patients; Ctrl NMZL: NMZLs from HCV negative patients; RLN: non-neoplastic Reactive Lymph Nodes. The level is reported as 2-Ct values. p values <0.1 are reported, and those < 0.05 are shown in bold. B and C: summary of fold-change (vs. reference Ctrl NMZLs and RLNs, respectively) and p-value (Mann-Whitney test). Fold-change was calculated as ratio between median level of each group vs. median level of the reference group.
