Figure 3.

Baseline CD4⁺/CD8⁺ T cell ratios were associated with specific antibody responses after vaccination in PLWH. HIV-1 infected participants were stratified into 3 subgroups according to their baseline CD4⁺/CD8⁺ T cell ratios (<0•6, 0•6∼1•0 and ≥1•0). RBD binding antibody (A), neutralizing antibody (B) and S2 binding antibody (C) responses were compared among the three subgroups. Statistical analysis for (A) was performed by the method of non-parametric t test and statistical analyses for (B) and (C) were done by the method of parametric t test.  Median ± IQR of each group is shown in (A). Mean ± SD of each group is shown in (B) and (C).
