Maternal weight loss from 2 to 24 wk compared with weight change ≥0. ARV, antiretroviral drug; BAN, Breastfeeding, Antiretrovirals, and Nutrition; LNS, lipid-based nutrient supplement.

There was a significant overall effect of birth months (December-August) compared with referent months based on a Wald test of whether the group of all birth month variables significantly differed from zero: Wald χ2 (9) 81.33; P < 0.001.
