1
Data were analyzed by using general linear models. Fe30F, 30 mg Fe and 400 μg folic acid; Fe60F, 60 mg Fe and 400 μg folic acid; MINIMat, Maternal and Infant Nutrition Intervention, Matlab; MMN, multiple micronutrient supplement.
2
Values are geometric means (95% CIs).
3
Values are loge mean differences (95% CIs).
4
Models adjusted for maternal formal years of education (none, 1–5 y, or ≥6 y), socioeconomic status (quintiles), food supplementation, week 14 micronutrient concentration (loge), and duration of supplementation.
