Fig. 3: Relative abundance of organisms in case vs. control stool samples.

a Relative abundance of organisms in case vs. control stool samples, grouped by advancing postnatal age. Green = obligate and facultative anaerobes, brown = gram negative bacteria, purple = gram positive bacteria. b Permuted spline tests for statistical significance in longitudinal microbiome data depicting Enterococcus (genus) abundance over advancing postnatal age in weeks (x-axis), in total case (group spline in red) vs. control samples (group spline in blue, p-value = 0.01).
