| Female sex | 0.614 | 1.54 (0.29 to 8.22) |
| Remote residential area | 0.439 | 2.20 (0.30 to 16.23) |
| Projectile mechanism of injury | 0.918 | 1.09 (0.21 to 5.67) |
| Associated zone 1 injury | 0.423 | 1.81 (0.42 to 7.75) |
| Associated zone 2 injury† | 0.860 | 1.14 (0.26 to 4.97) |
| Associated zone 3 injury | 0.011* | 7.60 (1.58 to 36.46) |
| Associated adnexal injury | 0.203 | 2.74 (0.58 to 12.88) |
