Higher Hb among children in intervention villages (OWL DID: +0.24 g/dL; HC +0.51 g/dL) vs. controls Among subset of children (3–5.9 mo at baseline), higher Hb and reduced anemia in HC villages (Hb DID: +0.76 g/dL*; anemia DID: −14.6pp*) vs. control. This evidence concerns the gene GSTM1 and anemia.
