Plus-minus values are means ± standard deviations. The denominator used to calculate the percentages of infants or mothers with a specific characteristic was the number for whom the characteristic was known. This number was the total number in each group, unless otherwise specified. No significant differences were found between the two groups. # Race or ethnicity was reported by patients' parents or guardians or determined by the physician on reviewing the charts.
