Data Collection
A structured questionnaire was used by a trained research nurse to
collect participant data. Data collected included demographics,
gestational ages at enrolment and delivery, duration of follow‐up during
the pregnancy and postpartum periods, antenatal complications,
postpartum complications, mode of delivery, and neonatal information.
Laboratory evaluations included complete blood count, blood screening
for malaria and spirometry. Study data were managed using REDCap
(Research Electronic Data Capture) electronic data capture tools hosted
at the Data Coordinating Center, Vanderbilt University Medical Center.
REDCap is a secure, web-based application designed to support data
capture for research studies, providing (a) an intuitive interface for
validated data entry; (b) audit trails for tracking data manipulation
and export procedures; (c) automated export procedures for seamless data
downloads to common statistical packages; and (d) procedures for
importing data from external sources.
