Among pregnant women (N = 547) who were not severely anemic at baseline.

Multivariate linear regression or binomial models were adjusted for mid-upper arm circumference (MUAC), World Health Organization human immunodeficiency virus (WHO HIV) disease stage, CD4 count, gestational age at enrollment, malaria infection, and treatment regimen.

RR = relative risk; CI = confidence interval.
