Model-based means (and 95% confidence intervals) for (A) CD4 and (B) CD8 cells/mm3 (n = 76 human immunodeficiency virus type 1 (HIV-1)–infected and n = 311 HIV-1–uninfected children), (C) IgG levels (mg/dL; n = 69 HIV-1–infected and n = 266 HIV-1–uninfected children), and (D) serum log10 HIV-1 RNA levels (HIV-1 RNA genome copies/mL; n = 67 HIV-1–infected children) by age according to HIV-1 infection status and Epstein-Barr virus infection status at each age. Means for CD4 and CD8 cell counts are cube-root transformations; IgG level is a geometric mean.
