Model was a logistic regression (Wald method). Dichotomized scales for binary logistic regression: normal and delayed/need to improve. p-values < 0.05 are highlighted in bold. * Breastfeeding group as reference. The SF group was not included in the model of form, content, and total score. ^† High socioeconomic status as reference. Socioeconomic status was not included in the model of form and use. CI: Confidence interval; OR: Odds ratio; PLON-R: Oral Language Task of Navarra-Revised; SF: Standard infant formula.
