Data are medians (interquartile range) or n (%). P values refer to overall differences across groups as derived from ANOVA for continuous variables (parametric test for normally distributed variables and nonparametric test for skewed variables), χ2 test for breast-feeding, or Fisher's exact test for smoking.
