Fig. 1 — a Large-scale cluster randomized trials in Bangladesh (n = 720 clusters) and Kenya (n = 702 clusters). Points indicate study clusters, with subdistricts and panel b insets outlined. b Clusters were geographically pair matched in blocks of 8 (Bangladesh) or 9 (Kenya) and then randomized. Children in the control and nutritional intervention clusters were included in the present analyses. c Sample sizes included in analyses for four representative outcomes, length-for-age z (LAZ), verbal communication scores (EASQ-C), diarrhea and Ascaris sp. infection. The Kenya trial was restricted from 89 to 72 blocks with a balanced set of control (2) and nutrition (2) clusters. Supplementary Information Tables 1 and 2 include sample sizes for all outcomes.
