Competing Interests

I have read the journal's policy and the authors have declared the following competing interests: Data collection was funded by the French Ministry of Health (Direction Générale de la Santé, French Ministry of Health). However we have the full-property of the data and the Health Ministry has no rights on the content of the analysis and the publications which could result from the use of the data. BV also benefited from the support of the “Drug-Safe” program from the French National Agency for Medicines and Health Products Safety (Agence Nationale de Sécurité du Médicament). Our professional statute warrants a total independency. We declare that we have no other conflict of interest. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
