Figure 5: Profiling anti-HPV and anti-MCV antibodies. The antibody levels and 95% CI are shown for (a) MCV VP1 and (b) E7 HPV-16 in the 23 control blood donors, 23 OLP, 23 KS, and 23 NHL subjects. The antibody levels for each individual are plotted on the Y-axis using a scale. The dashed line represents the cut-off level for determining seropositivity. values for the different groups were calculated using the Mann Whitney test.
