KEGG metabolic modules significantly associated with IBD status or subject metadata using a boosted general linear model. A multivariate analysis was performed to associate each metabolic module with a sparse selection of disease status and clinical metadata (selected through boosting; see Materials and methods). Each module and metadata in these associations is given with nominal p-values from the multivariate linear model and with Benjamini and Hochberg (BH) corrected false discovery rate (q-values) up to a threshold of 0.25.
