Competing Interests
R.E. Black has no conflict of interest. S. Muthayya and J.D. Sugimoto worked as consultants for Sight and Life, a humanitarian nutrition think tank of DSM. DSM is a global vitamin producer and has been a global partner of the United Nations World Food Programme since 2007. J.H. Rah was employed by Sight and Life when the manuscript was drafted. K. Kraemer is employed by Sight and Life, and F. Roos has been employed as a full-time biostatistician by DSM Nutritional Products since 2007. This does not alter the authors' adherence to all the PLOS ONE policies on sharing data and materials.
