---|---|---|---|---|
Primary | TMAO level | plasma and urine TMAO concentrations of oral carnitine challenge test | Before and 1 month after L-carnitine supplementation | |
Primary | Compositional and functional alterations of gut microbiota | The compositional and functional changes of gut microbiota will be evaluated by shotgun metagenome sequencing. Taxonomy will be calculated as relative abundance of species-level genome bins (SGBs) and specific bacteria genes will be quantified as Reads Per Kilobase per Million (RPKM). | Before and 1 month after L-carnitine supplementation |
