Comparison of fecal and blood metabolome reveals inconsistent associations of the gut microbiota with cardiometabolic diseases

Abstract

Here, analyzing paired fecal and blood metabolomics and metagenomics data in a large cohort, Deng et al. uncover disparate associations of the gut microbiota with cardiometabolic diseases when utilizing either fecal or blood metabolome data, suggesting that sampling criteria may be a relevant factor in metabolomics-based association studies.
