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. | ||||||||
*p Values were obtained from χ2 tests. | ||||||||
