For dichotomous outcomes, a method has been suggested by Di Pietrantonj for reconstructing the 2 × 2 table when the Odds Ratio (OR), the Standard Error (SE(lnOR)) and the sample sizes are provided. The method produces two possible 2 × 2 tables; and to select the correct ...

Contingency table analysis is rooted in work at the beginning of the 20th century; George Udny Yule first introduced the cross-product ratio (or odds ratio) as a formal statistical tool. The subsequent contributions by R. A. Fisher linked the Pearson and Yule methods to basic statistical method...
