| Feeding mode (breastmilk/formula) | 70/24 | 48/15 | 0.96 |
| Variable | HC mothers group | NB mothers group | P |
|---|---|---|---|

For numerical variables, the median and interquartile range are shown as the data did not display a normal distribution (Shapiro–Wilk test, P < 0.05). For categorical variables, the number of samples in each group is shown. The two groups were compared with Wilcoxon rank-sum tests for numerical variables and with Chi2 tests for categorical variables (Table S2).
