【摘要】 本文对同安原发性肝癌有关危险因素进行了研究。应用广义相对危险度函数模型处理数据,评判何种模型拟合最佳。结果提示:乙型肝炎病毒感染、家族肝癌史及人均收入低是其危险因素。多因素共同作用形式似一种偏向于相乘的结构。在研究多因素疾病时,有必要探讨因素间作用形式即资料符合什么模型结构。不同模型间数量上的差异对病因学的解释和公共卫生实践具有重要意义。更多还原

【Abstract】 This paper was to analyse the effect of risk factors of Primary hepatocellular carcinoma (PHC). The analysis was carried on using the family of relative risk functions to asses which scale could better explain the risk structure underlying the data. The results showed that HBV infection, the family of PHC and the low income were the risk factors of PHC. The results suggest that the combined effect of risk factors is near to multiplicative. Being able to discriminate between risk structures has important implications on causal inter pretation and public health practice.更多还原
