DALYs disability adjusted life years, CI confidence interval. This refers to constructed 95% confidence intervals as calculated in the probabilistic sensitivity analysis. Pre-school children from 0.5 to 4 years old; school age children from 5 to 14 years old; adults men and women from 15 to 64 years old

Using the attribution of anemia to iron deficiency of 25% for pre-school age children and 30% for school age children, 37% for women and 18% for men by Petry et al. [5]
