Figure 2.

Effects of antenatal micronutrient supplementation on offspring mortality from birth to age 7 years, expressed as hazard ratios (HR) and 95% confidence intervals (CI), by supplementation group, Nepal, 1999–2008. A) Folic acid-iron supplementation versus vitamin A alone (control group); B) multiple micronutrient supplementation versus vitamin A alone (control group). For interaction between preterm birth and multiple micronutrient supplementation, P < 0.1 (Cox proportional hazards model with a robust variance estimate). Body mass index is calculated as weight (kg)/height (m)².
