Figure 3. Surviving Penetrating Injury to the Brain (SPIN) score.
(A) Components of the SPIN score and assigned score points. (B) Estimated survival probability (y-axis) plotted against the total survival (SPIN score). (C) Comparison of the observed (red bars) to predicted (blue bars) proportion of survivors by SPIN score categories. Y-axis: percent of patients who survive at hospital discharge and 6 months after penetrating traumatic brain injury. X-axis: SPIN score categories. Data table: percent of predicted and observed patients in the entire cohort per SPIN score category. GCS = Glasgow Coma Scale; INR = international normalized ratio.
