|Entry Feature||Odds Ratio||95% Confidence Interval||p Value|
|Angiographic (continuous variable)|
|Myocardial jeopardy at 5 yrs (per 10% increase)||1.22||1.09–1.36||0.0003|
|Clinical (discrete variable)|
|Severe angina at entry (CHC 3, 4, or unstable angina)||2.20||1.17–4.14||0.01|
|Current or former smoker at baseline||1.91||1.09–3.35||0.02|
Other variables considered include age, gender, initial mode of revascularization (PCI or CABG), totally occluded lesion, diffuse lesion, number of significant lesions, history of diabetes, MI, or CHF, regular exercise at baseline, percentage of new disease at five years, percentage of disease progression at five years. In a separate model that included initial mode of revascularization (PCI or CABG), the interaction effect between mode of revascularization and percentage jeopardized myocardium at five years was not statistically significant (p = 0.51).
