Additional file 6: Figure S2A-E. Visual representation of the association between maternal characteristics and milk microbiota beta-diversity (Bray-Curtis metric). Principal coordinate analysis (PCoA, Bray-Curtis dissimilarity) plots comparing microbiota composition based on (A) maternal glucose tolerance, (B) mode of delivery, (C) pre-pregnancy BMI, (D) 3-month post-partum BMI, and (E) ethnicity. PCoA using the Bray-Curtis dissimilarity showed that microbiota profiles separated based on pre-pregnancy BMI (R2 = 0.037, p = 0.031), even after adjustment for maternal glucose tolerance status, mode of delivery, DNA extraction batch, and PCR sequencing batch. No statistically significant findings were observed between beta-diversity and glucose tolerance, mode of delivery, 3-month post-partum BMI or ethnicity. Abbreviations: GDM, gestational diabetes mellitus, IGT, impaired glucose tolerance; CS, C-section.
