Host factors dictate gut microbiome alterations in chronic kidney disease more strongly than kidney function - Nature Microbiology
A covariate-aware analysis reveals that microbiome changes in the gut of patients with chronic kidney disease are better explained by intestinal transit time than by kidney function.
