Mean hemoglobin and ferritin in children aged 12–59 months, Jordan 2002 and 2010.

Indicator	2002		2010		P-valuea
	n	Mean (95% CI)	n	Mean (95% CI)
Hemoglobin (g/l)b,c	1059	117.2 (116.3, 118.1)	902	118.4 (117.5, 119.3)	0.07
Ferritin (ng/ml)d	1056	18.1 (17.1, 19.2)	940	24.4 (23.0, 25.9)	<0.001

Abbreviation: CI, confidence interval. Note: the n’s are unweighted denominators for each subgroup. Means are weighted. CI, adjusted for cluster sampling design.

^a2002 and 2010 means for each indicator compared using weighted t-tests.

^bHemoglobin is not adjusted for altitude.

^cArithmetic mean.

^dGeometric mean.
