Multivariable results from metagenomic sequencing (species level taxa and MetaCyc pathways). Heat maps showing the direction and size of model coefficients as determined by MaAsLin2 modeling (A) significant taxonomic differences and (B) significant functional pathways that differed relative to VD-EBF at 6 weeks and relative to VD-≥6BF at 1 year. Figures include identified taxa with a FDR corrected q value < 0.25. VD-EBF, vaginally delivered and EBF; VD-FF, vaginally delivered and FF; CD-EBF, cesarean -delivered and EBF; CD-FF, cesarean -delivered who were FF; VD- ≥ 6BF, vaginally delivered who breast-fed for >6 months; VD- < 6BF, vaginally delivered who never breast-fed or breast-fed for <6 months; CD- ≥ 6BF, cesarean -delivered who breast-fed for ≥6 months; CD- ≥ 6BF, operatively delivered who never breast-fed or breast-fed for <6 months; FDR, false discovery rate.
