Ethics approval and consent to participate
: A formal ethics approval is not necessary because this study does not involve the human person but uses only health data. In accordance with European and French legislation, “(French translation) reference methodology MR-004 of the French National Agency regulating Data Protection (CNIL) covers the processing of personal data for purposes of study, evaluation or research that does not involve the individual. Specifically, these are studies that do not meet the definition of research involving the human person, particularly studies on the use of data” (Deliberation n° 2018–155 of May 3, 2018 published in the Official Journal of the French Republic n°0160 of July 13, 2018, text n° 110).” In accordance with the MR-004 of the French National Agency regulating Data Protection (CNIL), an administrative permission was required to access the raw data. Hence, there was no implication of any ethic comity to get permission to access the raw data. All patients participating in this study received written informed information and the opportunity to oppose the use of their data.
