Adjusted geometric mean plasma folate (A), vitamin B-12 (B), and TfR (C) concentrations at 24 wk postpartum in a sample of BAN study mothers who were untreated or given HAART with or without LNS. Values are geometric means and 95% CIs. (A and B) No HAART, no LNS: n = 237; no HAART, LNS: n = 238; NLF, no LNS: n = 43; NLF, LNS: n = 43; LPVr, no LNS: n = 60; LPVr, LNS: n = 67. (C) No HAART, no LNS: n = 237; no HAART, LNS: n = 238; NLF, no LNS: n = 44; NLF, LNS: n = 44; LPVr, no LNS: n = 60; LPVr, LNS: n = 67. Comparisons were made between no LNS and LNS within each drug category (no HAART, NLF, and LPVr) and between NLF or LPVr and no HAART within each LNS category. *,**,***Difference between adjusted means at either end of the bar: *P < 0.05, **P < 0.01, ***P < 0.001. BAN, Breastfeeding, Antiretrovirals, and Nutrition; HAART, highly active antiretroviral therapy; LNS, lipid-based nutrient supplements; LPVr, lopinavir/ritonavir; NLF, nelfinavir; TfR, transferrin receptor.
