Figure 2 Odds ratios for in-hospital adverse outcomes in patients with thrombus. These models were adjusted for the trial in which patients were enrolled, their age, history of angina, history of diabetes, prior percutaneous transluminal coronary angioplasty and prior coronary artery bypass grafting. Among all patients with thrombus, the odds of myocardial infarction (MI) were 1.33 and of death/MI were 1.30 relative to the odds of patients without thrombus. These odds were somewhat reduced (1.28 and 1.26, respectively), although still significantly different from patients without thrombus, when only patients without vein grafts were considered.
