A simple technique, developed in Phillips (unpublished Ph.D. dissertation, University of Windsor, Windsor, Ontario, 1987), is used to approximate cov(theta MH, pi), i = 1, 2, where theta MH is the Mantel-Haenszel log-odds-ratio estimator for a 2 x 2 x K table and the pi are the sample marginal proportions. These results are then applied to obtain an approximate variance estimate of an adjusted risk difference based on the Mantel-Haenszel odds-ratio estimator.
一种在菲利普斯（未发表的博士论文，温莎大学，安大略省温莎市，1987年）中开发的简单技术，用于近似协方差（θMH，π），i = 1, 2，其中θMH是2×2×K表的曼特尔-亨泽尔对数优势比估计量，π是样本边际比例。然后应用这些结果来获得基于曼特尔-亨泽尔优势比估计量的调整风险差异的近似方差估计。
