: In line with the French legislation on retrospective studies of de-identified data recorded during routine clinical practice, the study did not require approval by an institutional review board but was registered with the French National Data Protection Commission (<i>Commission nationale de l’informatique et des libertés</i>, Paris, France; reference: CNIL DEC20-308). The CNIL approved that all we needed was a letter of information to parents according ro reference methodology MR-004, deliberation no. 2018 − 155 of May 3, 2018. Each patient’s parent(s) received a study information sheet and could refuse the inclusion of their child.
