A time-sharing program written in BASIC language has been developed to compute exact confidence limits for the odds ratio parameter in a 2 x 2 table. The program offers the user a choice between the classical exact limits and limits based upon a recent redefinition of the exact p-value aimed at avoidance of conservatism in the classical procedure. The user selects the degree of confidence desired during a run of the program, which then computes the exact limits and p-value.?23Athor
