This study applied a matched cluster, controlled design, using community cluster as the unit of randomization. Communities were first matched during the formative research phase and randomized into treatment (Vita Mamba + deworming) or control (deworming) groups, using a simple experimental 1:1 design. The principal investigator generated the random allocation sequence and assigned the cluster to groups. Children were followed longitudinally for Hb concentration and anthropometric measures were taken at baseline (November 2014) and endline (June 2015). Parents were surveyed at baseline for household-level socioeconomic and demographic information; environmental conditions including water, hygiene, and sanitation; and child diet and morbidities.
