This study proposes and evaluates the theory that people who are susceptible to injury in residential fires are not susceptible to death in residential fires and vice versa. It is proposed that the population vulnerable to death in residential fires can be proxied by 'frailty', which is measured as age-gender adjusted fatality rates due to natural causes.
This study uses an ecological approach and controls for exposure to estimate the vulnerability of different population groups to death and injury in residential fires. It allows fatalities and injuries to be estimated by different models.
Frailty explains fire-related death in adults while not explaining injuries, which is consistent with the idea that deaths and injuries affect disjoint populations.
Deaths and injuries in fire are drawn from different populations. People who are susceptible to dying in fires are unlikely to be injured in fires, and the people who are susceptible to injury are unlikely to die in fires.
本研究提出并评估了以下理论，即在住宅火灾中易受伤的人不易在住宅火灾中死亡，反之亦然。有人提出，在住宅火灾中易死亡的人群可以用“脆弱性”来代表，这可以通过因自然原因导致的年龄-性别调整死亡率来衡量。
本研究采用生态方法并控制暴露因素来估计不同人群在住宅火灾中死亡和受伤的脆弱性。它允许通过不同的模型来估计死亡率和受伤率。
脆弱性可以解释成年人与火灾相关的死亡，但不能解释受伤，这与死亡和受伤影响不同人群的观点一致。
火灾中的死亡和受伤来自不同的人群。在火灾中易死亡的人不易在火灾中受伤，而易受伤的人则不易在火灾中死亡。
