"The protocol of the Gerocovid Observational study was reviewed and approved by the Ethics Committee of the Campus Bio-Medico University (Rome, Italy) and was subsequently ratified by the Ethics Committees at all participating centers. Written or dematerialized informed consent was obtained from all patients or their next of kin when applicable before enrolment. In case of impossibility in obtaining the patient's consent, a written declaration was collected by the local investigator, responding to applicable derogations during the COVID-19 pandemic. The study was registered in ClinicalTrials.gov (NCT04379440)."
