目的通过对400例与自行车有关的交通事故｛骑车205例,推车195例｝尸检材料进行研究统计,判断损伤部位、类型与骑推行自行车是否存在相关性;方法对400例交通事故尸检材料中记载的尸表损伤进行分析,首先把损伤部位、损伤类型和交通方式作为三个分类变量,利用列联表分别检验损伤部位和交通方式之间的独立性,损伤类型和交通方式之间的独立性。在发现损伤部位、类型与交通方式之间不独立之后,我们把每一种损伤部位和类型(共21种)作为一个指标,进行两总体之差检验,检验每个指标在两种交通方式下差异是否显著。结果通过对以上资料进行分析发现,两种交通方式下差异显著的指标分别是:小腿骨折、大腿上段内侧挫伤、膝关节内侧挫伤、会阴部挫伤、小腿挫伤。
OBJECTIVE To study the autopsy materials of 205 cases of bicycle-related traffic accidents (205 cases of bicycles and 195 cases of carts), and to determine whether there is correlation between the injury site and type and riding a bicycle. Methods 400 cases of traffic accident autopsy materials In the first paragraph of the analysis of the damage on the dead body, the first injury part, the type of injury and the mode of transport as three categories of variables, the use of contingency table separately test the independence of the injury site and mode of transport, type of injury and traffic between Independence. After finding the site of injury, and the independence of the type and mode of transport, we used each site and type of injury (a total of 21 species) as an indicator to test the difference between the two populations and test each indicator for the two modes of transport Is the difference significant? Results Based on the above data, it is found that there are significant differences among the two modes of transportation: the lower leg fractures, the medial upper thigh contusion, the medial knee contusion, the perineal contusion, and the calf contusion.
