Fig. 3. A comparison of alpha diversity between different levels of significant covariates of the probiotic-treated, preterm infant gut.

Boxplots of alpha diversity (Shannon index) for significant Tukey’s pairwise comparisons designated by lower case letters (where a is significantly different from b) on linear mixed-effects model. Annotation for Diet: B breastmilk, B/F breastmilk and formula and F Formula. a Box plot comparing alpha diversity at admission and discharge between different types of diet, b box plot comparing alpha diversity between sepsis diagnoses and c box plot comparing alpha diversity at admission and discharge between retinopathy of prematurity diagnoses.
