†
Anaemia is defined as Hb <11·5 g/dl in children aged 6–11 years and as Hb <12 g/dl in children aged 12–14 years( 49 ).
‡
Fe deficiency is defined as serum ferritin <15 ng/ml( 49 ).
§
Adjusted for elevated C-reactive protein (>10 mg/l) or elevated α1-acid glycoprotein (>1 g/l) by mathematical correction( 18 , 19 ).
||
Fe-deficiency anaemia is defined as Hb <11·5 g/dl plus serum ferritin <15 ng/ml in children aged 6–11 years and as Hb <12 g/dl plus serum ferritin <15 ng/ml in children aged 12–14 years( 49 ).
