Quantification of the dependence of the odds ratio on concomitant variables associated with each of several 2 X 2 tables, using a regression model proposed by Zelen [1971], is an important tool for retrospective studies in epidemiology, An "exact" analysis may be based on the conditional likelihood obtained by fixing all the marginal totals. A symptotically this approach is equivalent to use of an unconditional log-linear model. The method is used to reanalyze data reported by Kneale [1971] on the relationship between obstetric radiation and childhood cancer.
利用泽伦[1971年]提出的回归模型，对与几个2×2表格中的每一个相关的伴随变量的优势比依赖性进行量化，是流行病学回顾性研究的重要工具。“精确”分析可以基于固定所有边际总数后得到的条件似然性。渐近地，这种方法等同于使用无条件对数线性模型。该方法用于重新分析 Kneale[1971年]报告的关于产科辐射与儿童癌症关系的数据。
