Multivariable logistic regression: Odds ratio for CABG treatment (vs. PCI) with 95% Confidence interval. Patients with multi-vessel disease and those referred from centers with on-site cardiac surgery units, were more likely to be referred to CABG, while those with prior PCI or a previous MI were more likely to have been referred to PCI. Older age, gender and history of congestive heart failure were not associated with any particular revascularization strategy referral pattern. CABG, Coronary artery bypass graft; PCI, Percutaneous coronary intervention; MI, Myocardial infarction; CHF, Congestive heart failure; CAD, Coronary artery disease; OR, Odds ratio; CI, Confidence interval
