Notes:

^aResponses R₀ and R₁ were compared to response R₂; P < 0.05 was considered significant.

Abbreviations: CI, confidence interval; OR, odds ratio; R₀, stabilization or decrease of CD4 cell count compared to the baseline value; R₁, suboptimal immunological response; R₂, optimal immunological response.
