"This was an investigator-initiated study. The Institutional Review Boards (IRBs) from the coordinating sites (Emory University and Boston Medical Center) considered that the investigators did not have access to protected health information in this follow-up study, and thus no IRB oversight was required since the study did not meet the United States federal description of human subject research. Investigators sought local IRB or ethics approval when required by local regulations. Informed consent was waived because of the retrospective nature of this study and because the research was considered no more than minimal risk. The study was registered under NCT04934020."
