Slide 1 -- Title of Project and Presenter Affiliation

Slide 2 -- Map of CIREN Center locations across the country (Seattle,
Washington; Milwaukee, Wisconsin; Ann Arbor, Michigan; Philadelphia,
Pennsylvania; Baltimore, Maryland; San Diego, California; Falls Church,
Virginia; Winston-Salem, North Carolina)

This slide also shows where the data was collected from for this
analysis. The ability to look at cases from all CIREN centers enhanced
this analysis.

Slide 3 -- This slide outlines the two primary objectives of this
project, to identify predictive characteristics and generate research
hypotheses.

Slide 4 -- This slide outlines how this study looked at 5 years of data
from the entire CIREN network and compared those findings with previous
studies. It also explains how CIREN focuses on high severity crashes and
injuries.

Slide 5 -- This slide outlines the study group; 2,299 cases were pulled
from the data extracts, focusing on adults in frontal and side
collisions in vehicles with frontal airbags. Exclusion criteria is also
listed.

Slide 6 -- This slide explains the methods used in this analysis;
logistic regression models for each body region. The outcome was defined
as the presence of an injury scored as 3 or higher on the Abbreviated
Injury Severity (AIS) scale. A stepwise logistic regression was
performed and variables found to be significant were kept in the model.

Slide 7 -- This slide lists all independent variables used in this
analysis. For crash characteristics, the Principal Direction of Force
(PDOF) was defined as frontal, near side or far side. The change in
velocity (Delta V) was categorized as less than 20 kilometers per hour
(kph) and at 10 kph increments up to 60 kph. Curb weight was also used.

For occupant characteristics, age was categorized as 16 to 30 and then
by 10 year intervals. Weight, height, gender and belt use were also
looked at. Body mass index (BMI) was categorized as underweight, normal
weight, overweight and obesity.

Slide 8 -- This slide shows the number of cases that were excluded due
to specific criteria. The final study group consisted of 1,656 cases.

Slide 9 -- This slide shows a general breakdown of the study group by
age, gender and BMI.

Slide 10 -- This slide shows a general breakdown of the study group by
Delta V (in kph and miles per hour (mph)), restraints used and PDOF.

Slide 11 -- This slide shows a breakdown of injured body regions (by AIS
score) and injury severity score (ISS) group (a scoring method that
compiles the most severe injury in each body region).

Slide 12 -- This slide lists the six body regions that were found to
have significant associations with the factors listed previously (the
face and neck regions had too few numbers to analyze).

Slide 13 -- This table summarizes the occupant and crash factors that
were found to have a significant association with a body region with an
injury of AIS 3 or higher. The remainder of the presentation will
address the head, thorax and lower extremity regions.

Slide 14 -- This slide outlines other exclusions based on statistical
significance.

Slide 15 -- This slide lists risk factors associated with an AIS 3+
thoracic injury. It also lists characteristics that were found to be not
significant. Finally, it lists the odds ratios associated with the
remaining, significant factors.

Slide 16 -- This slide contains an excerpt from a previous study
conducted by the Fairfax CIREN Center. It illustrates the force needed
to break a rib based on the age of the occupant, the older the person,
the less force needed to break their rib.

Slide 17 -- This slide lists risk factors associated with an AIS 3+
lower extremity injury. It also lists characteristics that were found to
be not significant. Finally, it lists the odds ratios associated with
the remaining, significant factors.

Slide 18 -- This slide contains an excerpt from a previous study
conducted by the Fairfax CIREN Center. It illustrates the force needed
to incur a lower extremity fracture based on the age of the occupant,
the older the person, the less force needed to break their rib.

Slide 19 -- This slide contains an excerpt from a previous study
conducted by the Michigan CIREN Center. It illustrates the incidence of
femur fractures by age group, the younger population showed more
fractures than the older group.

Slide 20 -- This slide contains an excerpt from a previous study
conducted by the Michigan CIREN Center. It illustrates the incidence of
tibia fractures by age group, the older population showed more fractures
than the younger group.

Slide 21 -- This slide lists risk factors associated with an AIS 3+ head
injury. It also lists characteristics that were found to be not
significant. Finally, it lists the odds ratios associated with the
remaining, significant factors.

Slide 22 -- This slide is similar to slide 21; however the analysis was
repeated with the 51-60 age group as the reference group.

Slide 23 -- This slide contains an excerpt from a previous study
conducted by the Michigan CIREN Center. It illustrates the incidence of
head injury by age group, the oldest and youngest populations showed the
most injuries.

Slide 24 -- This slide is similar to slide 21; however the analysis was
repeated focusing on near and far-side impacts.

Slide 25 -- This slide is a continuation of Slide 24.

Slide 26 -- This slide contains an excerpt from a previous study
conducted by the Miami CIREN Center. It illustrates the higher
occurrence of near-side impacts and their likelihood to cause an injury
of AIS 3+.

Slide 27 -- This slide contains an excerpt from a previous study
conducted by the Miami CIREN Center. It illustrates the risk of injury
in near and far-side impacts adjusted by Delta V. It shows that the risk
of injury is higher for near-side impacts than far-side impacts.

Slide 28 -- This slide contains an excerpt from a previous study
conducted by the Michigan CIREN Center. It illustrates the incidence of
head injury in far-side impacts due to the presence of another occupant.

Slide 29 -- This slide is similar to slide 21; however the analysis was
repeated focusing on Delta V.

Slide 30 -- This slide is a continuation of Slide 29.

Slide 31 -- This slide is a continuation of Slide 30.

Slide 32 -- This slide is a continuation of Slide 31.

Slide 33 -- This slide lists the risk factors found to be associated
with thoracic injuries by the research team.

Slide 34 -- This slide lists the conclusions and risk factors found to
be associated with lower extremity injuries by the research team.

Slide 35 -- This slide lists the conclusions and risk factors found to
be associated with head injuries by the research team.

Slide 36 -- This slide lists the general conclusions found by the
research team.

Slide 37 -- This slide revisits the chart from Slide 13 and notes the
risk factors that were found to be associated with injuries in each body
region.

Slide 38 -- This slide lists research recommendations made by the
research team.

Slide 39 -- This slide lists groups that the research team would like to
acknowledge.

Slide 40 -- This concludes the presentation and asks for discussion.
