AIS-Abbreviated Injury Scale; shading represents relative percentage ranging from 0 (white) to 100 (black). For association of morbidities with number of body regions by Cochran-Armitage trend test: P<0.001 for any domain, feeding, and motor; P=0.02 for communication, P=0.03 for respiratory. For association with head injury, no comparisons are significant at the 0.05 level. For association with spine injury by Fisher’s exact test, P=0.009 for any domain, P=0.003 for motor, P=0.01 for sensory. For association with lower extremity injury by Chi-squared test, P<0.001 for any domain and motor, P=0.002 for feeding.
