The confidence limits for all parameters derived from a 2X2 contingency table are uniquely determined by the limiting matrices that arise from adding or subtracting certain values to or from the four cell entries. Various methods to determine these addends are discussed and a computer program is presented that produces reliable results. The limiting matrices thus produced bypass the more complicated expressions for the standard errors of the many epidemiological parameters that are used to interpret the 2X2 table.
由2×2列联表得出的所有参数的置信限，由对四个单元格条目进行加或减某些值而产生的极限矩阵唯一确定。讨论了确定这些加数的各种方法，并给出了一个能产生可靠结果的计算机程序。由此产生的极限矩阵避开了用于解释2×2表的许多流行病学参数标准误差的更复杂表达式。
