Even though this getting could reflect differences within the composition of gut microbiota involving men and ladies, offered evidence argues against this explanation [3]. Gender differences in intestinal absorption, metabolismand/or renal clearances could also be involved, but supporting proof, no less than in humans, is lacking so far. Smoking and alcohol consumption have been associated with reduced indoxyl sulfate levels and p-cresyl sulfate, though for the latter, the association was lost in multivariable analyses. The mechanisms underlying these associations are unclear. Despite the fact that a directTable 3.

Then, a mixed model with family members included as a random effect plus the covariables selected in the preceding step entered as fixed effects was used to calculate parameter estimates. The following variables had been offered to the stepwise regression model: sex, age (linear and squared term), systolic and diastolic blood stress, history of cardiovascular disease, antihypertensive drug intake, current smoking and alcohol intake, body mass index, diabetes mellitus, serum total cholesterol, triglycerides, serum creatinine and calculated creatinine clearance. doi:ten.1371/journal.p.
