Declarations

:

: Following the ‘Measures for the Ethical Review of Biomedical Research Involving Human Subjects’ of China, this retrospective study was granted ethical approval (Approval Number: K-W-2024-010) by the Institutional Review Board of the Ethics Committee at Tongji Hospital, affiliated with Tongji University in Shanghai. For research using human data with identifiable information, when the subject cannot be located and the research project does not involve personal privacy or commercial interests, the committee waived informed consent. Nevertheless, since the new-generation tetracyclines are available over the counter for children under the age of eight, it is imperative that their legal guardians be informed about the treatment and sign an informed consent form.
