Though this finding may perhaps reflect variations inside the composition of gut microbiota in between men and women, offered proof argues against this explanation [3]. Gender variations in intestinal absorption, metabolismand/or renal clearances could also be involved, but supporting proof, at the very least in humans, is lacking so far. Smoking and alcohol consumption have been connected with decrease indoxyl sulfate levels and pcresyl sulfate, even though for the latter, the association was lost in multivariable analyses. The mechanisms underlying these associations are unclear. While a directTable 3.

Then, a mixed model with family incorporated as a random impact as well as the covariables chosen within the previous step entered as fixed effects was used to calculate parameter estimates. The following variables have been offered for the stepwise regression model: sex, age (linear and squared term), systolic and diastolic blood pressure, history of cardiovascular illness, antihypertensive drug intake, existing smoking and alcohol intake, physique mass index, diabetes mellitus, serum total chol.
