EBV-specific IgG in BL patients with jaw tumors (n = 14) and abdominal tumors (n = 16). Plasma was diluted at 1:6400 and tested using a Luminex Bead Based array. Specific EBV antigens were (A) Zta-specific IgG, (B) EAd-specific IgG, (C) VCA-specific IgG, (D) EBNA1-specific IgG. The MFI of 75 of Luminex beads for each of the antigen tested is indicated on the y-axis. The differences between two study populations were compared using Mann-Whitney U test. p values of Mann-Whitney U tests are indicated in the figures. Horizontal bars represent median values per each study population.
