Development of Endothelial Biomarkers (NUTREND)

September 4, 2018 updated by: University Hospital, Clermont-Ferrand

Development of Endothelial Biomarkers for Use in Cohort Studies. Comparison With Reference Biomarkers.

The main objective is to develop and validate new endothelial function markers discriminating and reproducible by assessing the ability to reveal changes in endothelial function in response to positive and negative nutritional stimuli.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
