Despite being eligible to receive MNP since weaning and thus exposed to the MNP since infancy, the prevalence of anaemia (Hb < 110 g/L; primary outcome) in 3‐year‐old children was similar between children receiving MNP and those who did not (57.6% intervention arm vs. 60.1% control arm, respectively; aOR 0.84 [95% CI 0.59–1.21]; p = 0.352); likewise moderate‐to‐severe anaemia (Hb < 100 g/L; 27.1% vs. 31.3%; aOR 0.70 [95% CI 0.47–1.04]; p = 0.081, Table 2a). The gene discussed is GSTM1; the disease is anemia (phenotype).
