| 摘 要： | 根据不同的研究设计，在队列研究中可分别估计累积发病率比（ＣＩＲ）、发病密度比（ＩＤＲ）和发病比值（ＩＯＲ）。当疾病罕见时，这３个比之值很接近。在病例对照研究中，是否可用暴露比值比（ＥＯＲ）作为ＣＩＲ或ＩＤＲ的无偏估计，取决于抽样方法和疾病率高低。本文还讨论了在不同抽样设计下ＥＯＲ与ＣＩＲ或ＩＤＲ之间的关系。

| Abstract: | Cumulative incidence ratio (CIR), incidence density ratio (IDR)and incidence odds ratio(IOR)can be calculated respectively in cohort study according to various study designs. The values of the three ratios given above are very close when the disease under study is rare. It depends upon the sampling methods and the size of the disease rate whether exposure odds ratio (EOR) in case-control studies can be used to estimate the CIR or IDR. The relationship between EOR and CIR or IDR under various sampling methods has been discussed in this paper. |
