Multivariable logistic regression was used to construct a model to predict significant coronary artery disease from data on 348 patients with valvular heart disease. Forward stepwise selection was used.The final model contained seven variables.The regression () coefficient for having a family history of ischemic heart disease (coded as 0=No, 1=Yes) was 1.167.

Given the above information, if we wanted to calculate for the odds ratio, and ₁=1.167, what would ₀ be?
