A, car accident; B, motorcycle accident; C, bicycle accident; D, pedestrian accident; E, fall down; F, slip and rolling down; G, crush; H, assault; I, others; AIS, abbreviated injury scale; AIS1, head and neck AIS; AIS3, chest AIS; AIS4, intra-abdominopelvic organ AIS; AIS5, extremity and pelvic bone AIS. ^aSignificant difference was observed between AIS1 and AIS3 or AIS4 or AIS5 as a result of post hoc analysis. ^bSignificant difference was observed between AIS3 and AIS4 or AIS5 as a result of post hoc analysis. ^cSignificant difference was observed between AIS4 and AIS5 as a result of post hoc analysis.
