Odds ratios for anaemia, iron deficiency, malaria and inflammation prevalence

	Effect of iron fortified complementary food		Effect of intermittent preventive treatment of malaria
	Received CF-FeFuma	n = 250	Received IPTa	n = 251
	No CF-FeFuma	n = 252	IPT-placeboa	n = 251
Odds ratiosb of anaemia (Hb concentration <11 g/dl) (95 % CI)
6 months	0.64	(0.33 to 1.25; P = 0.19)	0.46	(0.24 to 0.90; P = 0.023)
9 months	0.85	(0.43 to 1.68; P = 0.64)	0.46	(0.23 to 0.90; P = 0.024)
Odds ratiosc of iron deficiency (plasma ferritin concentration <30 µg/l) (95 % CI)
6 months	0.28	(0.14 to 0.56; P < 0.001)	1.52	(0.76 to 3.04; P = 0.23)
9 months	0.19	(0.09 to 0.40; P < 0.001)	1.64	(0.79 to 3.42; P = 0.19)
Odds ratiosb of malaria prevalence (P. falciparum) (95 % CI)
6 months	1.17	(0.68 to 2.01; P = 0.58)	0.59	(0.34 to 1.02; P = 0.057)
9 months	1.30	(0.71 to 2.39; P = 0.39)	0.61	(0.33 to 1.12; P = 0.11)
Odds ratiosb of the inflammation statusd (95 % CI)
6 months	0.66	(0.37 to 1.19; P = 0.17)	0.52	(0.29 to 0.94; P = 0.030)
9 months	0.82	(0.44 to 1.51; P = 0.52)	0.77	(0.42 to 1.43; P = 0.41)

^aAssignment at baseline

^bAdjusted for age

^cAdjusted for age and CRP concentration

^dInflammation is defined as CRP >5 mg/l and/or AGP >1 g/l

Odds ratios were assessed in 12- to 36-month-old Ivorian children at 6 and 9 months. The estimations are based on a 2 × 2 factorial analysis using a logistic regression model taking into account random effects
