Restraint status, front row seating, and serious injury by child age group among three driver groups (unweighted n = 19 059); values are weighted % (unweighted n)
| Appropriate restraint | Inappropriate restraint | No restraint | p Value* | Front row seating | p Value* | Serious injury | p Value* | |
|---|---|---|---|---|---|---|---|---|
| Note: There were no missing data for serious injury; the weighted distribution of missing data for the following variables was: 0.02% (unweighted n = 13) for child’s age, 0.02% (unweighted n = 58) for front row seating, 0.3% for restraint status (unweighted n = 111). Because of missing data, only valid percentages were reported. | ||||||||
