The unadjusted RR values were obtained from log-binomial regression models with the stratification factors of site and HIV status (known positivevsnewly diagnosed HIV infection) included as covariates. The adjusted analyses were done using several other prespecified baseline covariates in addition to HIV status and site, including gravidity, malaria status, socioeconomic status, season (average rainfall in the last 6 months before delivery), and malaria transmission intensity by study site (based on the prevalence of malaria at enrolment, continuous). NA=not applicable. RR=risk ratio. *Composite for low birthweight, small for gestational age, and preterm birth. Fetal loss included miscarriage and stillbirth.
