Data were analyzed by using general linear models. **Different from the lowest tertile, P < 0.01. 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.
Values are geometric means (95% CIs).
Values are loge mean differences (95% CIs).
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 in the analyses.
