| Lived, n (%) | Died, n (%) | Total, n (%) | Chi-square a | |
|---|---|---|---|---|
| 325 (52.3) | 296 (47.7) | 621 (100) | χ 2 ( p value) | |
| Rating | 5.8 (0.2159) | |||

aChi-square and p value expressed are for the relationship between rating (including unrated) and mortality. This includes all side crash test ratings (rollover and non-rollovers). Sensitivity analyses were performed with and without rollovers, but did not change the findings.
