: This study is based on anonymized patients’ medical data<i>,</i> including a self-administered questionnaire used in routine care. Completion of the self-administered questionnaire was proposed only to patients who understood written French, by the reception agent (verbal information) before the consultation. Patients were informed that completion of the self-administered questionnaire was optional and that non-participation would not affect care. Moreover, patients were informed by poster in the center and on the welcome page of the self-administered questionnaire of their right to object to the use of their data for research purposes (written information). This procedure complies with French law, as observational studies conducted on previously collected data require individual information and absence of patient objection (no explicit consent is required). Use of these data for research received institutional review board approval from the French Data Protection Authority (authorization CNIL no. 2005208 v0). This procedure complies with the European General Data Protection Regulation and this study has been declared to the AP-HP (Paris hospitals) Data Protection Office (no. 20190409164510).
