All values are means ± SDs. ExBF, exclusive breastfeeding; ExBF = 1 mo, ExBF for 1–1.9 mo; ExFM20, exclusively fed formula containing standard caloric density of 0.67 kcal/mL (equivalent to 20 kcal/oz); ExFM22+, exclusively formula-fed and received high caloric density formula [≥0.74 kcal/mL (≥22 kcal/oz)] for some duration during infancy. Wisconsin scores range from 0 (best) to 100 (worst), and Brasfield scores ranged from 25 (best) to 0 (worst). Values followed by the same superscript letter were not significantly different. P values were calculated by using the chi-square test.
