The data are presented as means ± SD (n). Differences in measures between groups were evaluated with the use of a parametric curves mixed model with the stratification factors as a fixed effect, and each subject's intercept and slope as random effects. *P < 0.05 for Concept compared with Control; **P < 0.01 for Concept compared with Control; no statistical testing compared to breastfeeding was done. IMF, infant milk formula.
