Figure 3: Profiling anti-KSHV antibodies. The antibody levels and 95% CI for (a) K8. 1, (b) ORF38, (c) LANA, and (d) v-cyclin 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 and is derived from the mean plus five standard deviations of the antibody values of the controls. values for the different groups were calculated using the Mann Whitney test.
