Limitations and caveats
The observed placental malaria rate was lower than expected causing the study to be under powered. After review of a futility analysis, the Sponsor and DSMB recommended allowing the study to conclude as planned and not to increase the sample size.

Registered outcomes14

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryIncidence of Placental Malaria Infection Based on HistologyAt delivery: Approximately 12-36 weeks after enrollment
The placenta was collected at the time of delivery for examination by histology to determine malaria infection. Malaria infection was concluded if histology identified parasites or malaria pigment in the placental tissue.
SecondaryIncidence of Placental Malaria by Placental Impression SmearAt delivery: Approximately 12-36 weeks after enrollment
Maternal participants were followed to outcome of the pregnancy. The outcome measure provides the incidence of malaria infection in the placenta based on diagnosis by positive placental impression smear results.
SecondaryIncidence of Maternal Anemia (Hemoglobin < 10 Grams/Deciliter)From enrollment until delivery, approximately 12-36 weeks
Maternal participants were followed to outcome of the pregnancy. The outcome measure provides the incidence of anemia among maternal participants during pregnancy . Anemia is defined as having a hemoglobin value less than 10 grams/deciliter (gm/dL).
SecondaryIncidence of Maternal Severe Anemia (Hemoglobin < 7gm/dl)From enrollment until delivery, approximately 12-36 weeks
Maternal participants were followed to outcome of the pregnancy. The outcome measure provides the incidence of severe anemia among maternal participants during pregnancy. Severe anemia is defined as having a hemoglobin value less than 7 gm/dl.
SecondaryIncidence of StillbirthAt delivery: Approximately 12-36 weeks after enrollment
Maternal participants were followed to outcome of the pregnancy. The outcome measure provides the incidence of participants' deliveries whose outcome was stillbirth, defined as an infant born without any signs of life at 28 weeks or greater of gestation.
SecondaryIncidence of MiscarriageAt delivery: Approximately 12-36 weeks after enrollment
Maternal participants were followed to outcome of the pregnancy. The outcome measure provides the incidence of participants' deliveries whose outcome was miscarriage, defined as an infant delivered without any signs of life at less than 28 weeks of gestation.
SecondaryIncidence of Preterm DeliveryAt delivery: Approximately 12-36 weeks after enrollment
Maternal participants were followed to outcome of the pregnancy. The outcome measure provides the incidence of participants' deliveries whose outcome was preterm delivery, defined as delivery less than 37 weeks of gestation. The outcome of the delivery was not considered, and could have been live birth, stillbirth, or miscarriage.
SecondaryInfant Mortality Rate to 14 Weeks of AgeFor 14 weeks after delivery.Infants were followed from the time of delivery until 14 weeks of age. This outcome measure provides the incidence of infants who died within 14 weeks of delivery.
SecondaryIncidence of Low Birth Weight (LBW) (Birthweight < 2500 Grams)At delivery: Approximately 12-36 weeks after enrollmentMaternal participants were followed to outcome of the pregnancy. The outcome measure provides the incidence of infants whose birthweight was less than 2500 grams.
SecondaryIncidence of Intrauterine Growth Restriction (IUGR)At delivery: Approximately 12-36 weeks after enrollment
Infants were followed from the time of delivery until 14 weeks of age. This outcome measure provides the incidence of infants with IUGR at delivery. IUGR is defined as weight below the 10th percentile for gestational age based on the World Health Organization (WHO) fetal growth curve. This classification is supported by literature resulting from the INTERGROWTH-21st Project; José Villar.
