Microbial genera associated with IBD status and OTU type. Fold-change is shown for genera associated with CD (vs non-IBD), UC (vs non-IBD), or OTU type (2 vs 1) with q less than .05 in multivariate DESeq2 models including sex, Jewish ancestry, current anti–tumor necrosis factor therapy, mode of delivery, family group, IBD diagnosis, and OTU type as covariates. Some taxa represent unclassified members of the indicated family (f) or order (o).
