1 Data were described by the mean ± standard deviation or median (25th and 75th percentiles) for continuous variables and frequency (percentages %) for categorical variables. sn-2 = the high sn-2 palmitate infant formula, in which 46.3% of the PA was esterified to the sn-2 position, BF = breast-fed, and Control = the infant formula in which 10.3% of the PA was esterified to the sn-2 position. 2 A significant difference in the delivery mode was observed between the sn-2 group versus the BF group (p < 0.001) and the control group versus the BF group (p < 0.001) based on the chi-square test. 3 A significant difference in the maternal education level was observed between the sn-2 group versus the BF group (p = 0.003) and the control group versus the BF group (p = 0.002) based on the chi-square test. BMI = body mass index.
