About the dataset

Primary description: Traumatic brain injury data repository

The Federal Interagency TBI Research (FITBIR) informatics system is hosted in collaboration between the NIH and the UK Department of Defense, as a public dataset for research into traumatic brain injury (TBI). The consortium includes multiple studies with varying data collection procedures, all focused on TBI. Data is publicly available via [https://fitbir.nih.gov/].
