Figure 2: Anti-p23 and p18 antibodies in the uninfected blood donors and HIV-infected subjects. The geometric mean titer and 95% CI for (a) p23 and (b) p18 EBV antibodies in the 23 control blood donors, 23 OLP, 23 KS, and 23 NHL subjects were plotted on the Y-axis using a log10 scale. Each symbol represents a sample from one individual. The dashed line represents the cut-off level for determining seropositivity. values for the different groups were calculated using the Mann Whitney U test.
