Figure 4. Towards prediction of the origin of baby stool microbiota by dyad analysis. (A) The percentage of baby stool microbiota SVs shared between the same baby’s saliva samples, or their maternal vaginal samples. Box plot whiskers represent the minimum and maximum. (B) PCA biplot based on sample-wise CLR-transformed Aitchison distance. Each point represents a baby stool sample. Strength and association for genera (SVs) are depicted by the length and direction of the gray arrows, respectively. Samples are colored by delivery method and shaped by sex; ellipses represent the 95% confidence intervals of the delivery method. (C) Beta diversity (Aitchison distance) between baby stool samples and prenatal vaginal samples compared based on clinical factors. CLR: centered log ratio; PCA: principal components analysis; SVs: sequence variants.
