Change in haemoglobin concentration from Week 0 to Week 24 in children who were non-anaemic (haemoglobin concentration ≥ 110 g/L), mild anaemic (100-109 g/L), and moderate to severe anaemic (< 100 g/L) at Week 0. The box indicates the range of the 1st to 3rd quartile with central line at median; Vertical bars indicate the 1.5 times inter-quartile range outside 1st and 3rd quartiles. Within each panel, groups with different letters have significant difference (Mann Whitney U test, P < 0.05).
