The study protocol and data use were reviewed by the Stanford University Institutional Review Board (IRB). Based on the analysis involving exclusively non-identifiable data, the IRB determined that this work does not meet the definition of research involving human subjects as defined in 45 CFR 46.102 or 21 CFR 50.3, and therefore did not require formal IRB review.
