From: Development of the preterm infant gut and gastric residuals microbiome

A Microbial profiles of 132 stool samples. Each bar represents a single sample, and samples are grouped according to their assigned cluster. Bars are colored based on the taxa. B Principal coordinate analysis (PCoA) of stool samples. Each sample is represented as a dot on the plot and is colored according to its assigned cluster. C Comparison of the community evenness (Shannon index) of stool samples between clusters. Boxes show the median and represent the 25% and 75% quantiles, whiskers extend to 1.5 times the interquartile range from box edges. Each dot represents a sample, and the number of samples within each cluster is noted under each box. p-value was calculated using a two-sided Kruskal–Wallis test. D, E Comparison of the birthweight and gestational age at birth, respectively, between clusters of subjects’ first samples. For each infant, the first sample was used to categorize the infant to a specific cluster. Box statistics as in (C) F Dynamics of early life stool microbiome stability. Lines connecting between the first (left) and last (right) samples represent the trajectory of stool microbial composition of subjects throughout hospitalization. The width of the lines connecting the columns is proportional to the number of infants sharing this trajectory. Clusters appear as the y-axis and are colored according to the representative bacteria.
