Fig. 2. Univariate analyses exploring changes in the gut microbiome of probiotic-treated, preterm infants between admission and discharge.

a Principal coordinate analysis plot for admission versus discharge based on Bray–Curtis dissimilarity matrix (p < 0.01 and R² = 0.06), b box plots of alpha diversity for admission versus discharge and c table of differential abundance testing for admission versus discharge (base value is admission). p-adj Adjusted p value, lfc log-fold change, lfcSE log-fold change standard error. **p < 0.01 and ***p < 0.001.
