Eligibility

Recruits 150 Protected populations are explicitly excluded per the criterion: "Protected populations according to the French public health code"; the trial's population settings indicate isVulnerablePopulationSelected:false. Absence of signed consent is an exclusion ("Absence of signed consent"), so written informed consent from the adult participant is required; no paediatric assent procedures are indicated because minimum age is 18..

Pregnancy Exclusion
Pregnant, breastfeeding or lactating women
