Note. GSW = gunshot wound; ISS = injury severity score; SBP = systolic blood pressure. GSW mortality is a subset of GSW frequency. Column totals should approach 100% for each variable within each column. The totals may not add to 100% because of a small amount of missing data.
a
An ISS > 16 is associated with higher likelihood of mortality.
