Summary data in the bottom row are provided as mean +/− standard deviation except for GCS and DRS scores, which are reported as median (range). Abbreviations: crani hemicraniectomy, DTI diffusion tensor imaging, EVD external ventricular drain, DRS disability rating scale, GCS admission Glasgow Coma Scale score, MVA motor vehicle accident, RH rehabilitation hospital, TBI traumatic brain injury. The IMPACT score is reported for the complete IMPACT model (core + CT + lab data elements), based upon clinical, imaging, and laboratory data recorded at the time of admission. Scores were calculated using the online IMPACT prognostic calculator (http://www.tbi-impact.org/?p=impact/calc). Of note, we report the IMPACT model’s predicted probability of a favorable outcome at 6 months. Subject 8 did not have DRS data recorded (−−) at the time of RH discharge
