Data collection at baseline, midline and endline included one venous sample (3ml) from the infant, HemoCue (Model 301) measurement to assess severe anemia (7 <g/dl) with appropriate referrals as mentioned earlier. Ethylenediaminetetracetic acid (EDTA) Vacutainers (BD ; catalog number 368841) for whole blood and plasma analyses and Trace Element Serum Separator Tube Vacutainers (BD; catalog number 368380) for serum analyses will be used for the sample collection with butterfly needles (21 or 23 gauge). Samples will be immediately placed in a super cooler tube rack and transported back to the lab within five hours where they were processed immediately. Questionnaires will be administered to assess socio-economic status, infant and young child feeding practices, morbidity (past week), household food security along with a 24 hour diet recall. Data was uploaded daily through cellular network, stored on Formhub and then Ona organization servers.
