TABLE 2.

Iron status of Chilean 12-mo-old infants by iron-supplementation condition¹

	No added iron (n = 534)	Low iron (n = 405)	High iron (n = 718)
Anemia [n (%)]	138 (25.8)^a	20 (4.9)^b	28 (3.9)^b
Iron deficiency anemia [n (%)]	120 (22.5)^a	17 (4.2)^b	21 (2.9)^b
Iron deficiency without anemia [n (%)]²	157 (29.5)^a	145 (36.7)^b	111 (15.6)^c
Iron deficiency total [n (%)]²	277 (52.1)^a	162 (41.0)^b	132 (18.6)^c

Statistical significance of group comparisons was based on Fisher’s exact test. Values in a row with different superscript letters are significantly different.

n = 532, 395, and 710 for no-added-iron, low-iron, and high-iron groups, respectively, because iron status could not be classified in the nonanemic infants who had ≥1 missing iron measure.
