This study was registered on ClinicalTrials.gov (identification number: NCT02175030) on June 26, 2014. The date of initial participant enrollment was on August 2016.
Individual participant data will be available (including data dictionaries). Complete deidentified patient dataset will be shared. The study protocol is available online associated with the publication of the study’s primary outcome at: https://www.nejm.org/doi/suppl/10.1056/NEJMoa2022141/suppl_file/nejmoa2022141_protocol.pdf. The data will be available from date of publication to 2 years after publication. Data will be made available for researchers with a query that can be addressed with the dataset. The research team will review data requests and provide the data for any valid research project or verification of results by any interested party with a legitimate interest. Data can only be transferred after obtaining a data transfer agreement between the University of Utah and the requesting institution’s investigator.
