Text: These analyses were performed using DISC study data that are available in identifiable form within the firewall used by the Department of Veterans Affairs (VA). The data are located in a secure research environment known as the VA Informatics and Computing Infrastructure (VINCI). Only aggregate summary statistics and results of our analyses are permitted to be removed from behind the VA firewall in order to comply with general regulatory constraints and VA privacy and data security policies. These restrictions support patient privacy and confidentiality. Those wishing to access the DISC study data are welcome to contact the Associate Chief of Staff for Research and Development at the VA Pittsburgh Healthcare System (Steven Graham, MD: Steven.Graham@va.gov) to discuss the details of the VA data access approval process. A de-identified dataset can be made available upon request pending ethical approval and in accordance with VA guidelines.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
