b Weights provided by the Healthcare Utilization Project in the data files were applied to obtain national estimates. Values shown are rounded to the nearest patient, which explains slight differences in totals.
c The Barell Injury Diagnosis Matrix18 is a tool for standardizing the description of injury type and body region of injury using International Classification of Diseases, Ninth Revision, Clinical Modification codes.14
d Cells with counts <11 are not shown.
e Total is not 51 151 because of rounding errors; each category is rounded to the nearest whole patient (injury).
