| Adjusted OR (95% CI) | Adjusted p value | |
| Rib fractures >6 | 1.19 (0.30 to 4.68) | 0.806 |
| Severe rib fractures >3 | 0.62 (0.01 to 94.53) | 0.853 |

| Bilateral rib fractures | 0.33 (0.09 to 1.23) | 0.097 |
| First rib fracture | 1.83 (0.36 to 9.21) | 0.466 |
| At least one fracture in three anatomic locations | 0.29 (0.07 to 1.13) | 0.074 |
