¹Values in parentheses are mean percentile values, calculated on the basis of the Centers for Disease Control and Prevention growth reference (24). All other values are means ± SDs. Fe, iron supplementation group; Plac, placebo group.

²Significantly different from corresponding value in Fe group, P < 0.05 (ANOVA and F test).
