a
Unless otherwise indicated, data are expressed as number (percentage) of patients. All numbers and percentages are accounted for by weight.
b
Calculated using univariate linear regression for continuous variables and Pearson χ2 test for binary variables.
c
Calculated using the Abbreviated Injury Score for splenic injury (range, 1-5, with higher scores indicating greater severity of injury).
d
Cell size is too small to report for some subcategories, per the Healthcare Cost and Utilization Project data use agreement.
