Fig. 7From: HIV-Tat immunization induces cross-clade neutralizing antibodies and CD4+ T cell increases in antiretroviral-treated South African volunteers: a randomized phase II clinical trialChanges from baseline of CD4+ T-cell number in vaccinees and placebos. Baseline values (left panel) and changes from baseline (right panel) of CD4+ T-cell counts in vaccinees (n = 99) and placebos (n = 100). Data are presented as mean values with standard errors. Longitudinal analysis for repeated measures by the generalized estimating equations method was applied for the analysis. p values assess the changes from baseline within and between treatment groupsBack to article page
