Figure 1: HIV antibody profiling in the uninfected blood donors and HIV patients with OLP, KS, and NHL. The antibody level and 95% CI for (a) gp41 (b) RT, (c) p24, and (d) HA2 influenza antibodies in the 23 control blood donors, 23 OLP, 23 KS, and 23 NHL subjects were plotted on the Y-axis using a 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 5 standard deviations of the antibody values of the controls. values for the different groups were calculated using the Mann-Whitney test.
