Summary of bacteria associations with breastfeeding and formula feeding in univariate Chi² testing (Fig. 3) and PLS modelling loading scores (for Model 2 see Fig. 3). All PLS models employ the same y and x variables. Model 2 comprises exclusively breastfed and exclusively formula fed infants (n=65), Model 3 (n=35) and Model 4 (n=30) are as Model 2 but restricted to vaginally and caesarean section delivered infants, respectively.
