Comparison of enrollment characteristics
Although this study achieved more than the anticipated sample size for BW in both study arms, 29.2% of the pregnant women in the intervention arm and 33.7% in the control arm did not have BW data and were thus considered lost to follow-up. We compared selected characteristics of the participants across the four groups: Intervention-with outcome; Intervention- LTFU; Control-with outcome; and Control-LTFU. As shown in Table
