Poisson Regression, Adjusted Relative Rate of Injury Site and Type
| Injury Category | RR | 95% CI | χ2 | P Value |
|---|---|---|---|---|
| Note: Sex, age, and race are included as covariates in each model, and relative rates are for children with hearing loss compared to controls. Only outcomes with at least 10 occurrences in the hearing loss and comparison group are included. | ||||
| RR = relative rate; CI = confidence interval. | ||||
| Any injury | 1.98 | 1.71–2.30 | 82.13 | <.001 |

| Upper extremity | 2.28 | 1.80–2.87 | 47.99 | <.001 |
| Lower extremity | 1.88 | 1.42–2.49 | 19.54 | <.001 |
| Fracture | 2.02 | 1.37–2.99 | 12.61 | <.001 |
| Sprains and strains | 1.64 | 1.14–2.38 | 7.02 | .008 |
| Open wound | 1.92 | 1.41–2.63 | 16.75 | <.001 |
