Emerging evidence indicates that the gut microbiota influences lipid metabolism, although findings across studies have been inconsistent. In this cross-sectional investigation, we analyzed the composition of gut microbiota, associated metabolic pathways, predicted gut metabolites, and the resistome in 1,384 participants (including 895 individuals with dyslipidemia and 489 controls) through shotgun metagenomic sequencing.
