Although the impact of traffic crashes is very high in Iran, there are few works on the association of crash-related factors with injury severity. This study was conducted on 145 drivers injured on the Qazvin-Loshan road in order to assess this association. The New Injury Severity Score (NISS), based on the conditions of the injured drivers during their first visit to regional hospitals, was used as the main outcome measure. Multiple linear regression analysis was performed by considering logarithmic scale for NISS as response variable and adjusting for the confounding effects, including the transfer to hospital variables. The results showed that high-vehicle damage (i.e. damage with repair cost more than 25% of the pre-crash value of the driver's vehicle) and being trapped inside the motor vehicle raised the NISS by 5.25 (95% confidence interval (CI) 2.51-10.71) and 2.34 (95% CI 1.20-4.67), respectively.
尽管交通事故在伊朗的影响非常高，但关于与事故相关因素与伤害严重程度的关联的研究很少。本研究对 145 名在 Qazvin-Loshan 道路上受伤的驾驶员进行了研究，以评估这种关联。新损伤严重程度评分（NISS）是根据受伤驾驶员在首次前往地区医院时的情况计算得出的，作为主要观察结果。考虑到 NISS 的对数尺度作为响应变量，并调整了混杂效应，包括向医院转移变量，进行了多线性回归分析。结果表明，车辆损坏严重（即修复费用超过驾驶员车辆碰撞前价值的 25%）和被困在汽车内，会使 NISS 分别增加 5.25（95%置信区间（CI）2.51-10.71）和 2.34（95%CI 1.20-4.67）。
