| 1 | 56 | 10.7 |
| 2 | 30 | 6.7 |
| 3 | 37 | 32.4 |

The probability in the study population of having a BCVI with this score; dashes in this column denote missing data because of no patients with this score (the statistical significance of the model was p < 0.001.
In the single study cohort from Primary Children's Hospital, a patient with a score ≤2 had a 7.9% probability of blunt cerebrovascular injury and a patient with a score ≥3 had a 39.3% probability of blunt cerebrovascular injury.
