Relative abundance of bacterial taxa in individual participants. Compositional bar plot shows the mean relative abundance at the genus level for each individual participant at axilla, ear, and groin sites for samples collected on days 1, 7, 14, and 21. Genera that had a relative abundance of <10% are listed as “other”.(Quantitative PCR data for Alpha-diversity metrics for body site: axilla, ear, and groin.

DNA in ng was measured using a standard curve and converted to total genomes per swab. The median for each arm/time point is represented by a black bar (when a median value is 0, the bar is not shown). Each time point was compared between the intervention and control arms using a Mann–Whitney test. Comparisons with significant differences are denoted in each figure (* = Demographic characteristics of very preterm infants in control and intervention arms *.* Data are expressed in medians.Bacterial genera with relative abundances that differed between body sites or with age at sampling. Differential abundance testing was performed with a mixed effects model in MaAsLin2, using Sample ID as a random effect and body site and age at sampling as fixed effects.
