Then PC was calculated with excess relative risk coefficient indirectly deduced from related animal experiment. 再利用间接导出的相应的致癌超额相对危险系数计算肿瘤来自所受照射的病因概率。
A linear combination between the additive and multiplicative model was used to transfer excess relative risk ( ERR ) estimates of LSS data to Chinese population. 采用相加、相乘模型的加权线性合并方法将LSS人群辐射致癌超额相对危险转换至中国人群。
There are two conditions to calculate PC, first is to estimate the cancers excess relative risk by analyzing epidemiological data, and second is to determine organ dose of the cancer site. 病因概率计算基于器官进行,需要两个条件:一是利用流行病学资料估计器官发生癌症的超额相对危险(excessrelativerisk,ERR),二是确定患者的器官剂量。
