3. Figure 2
Event-free (no recurrence of angina, myocardial infarction, PTCA reintervention, death) survival curves for patients undergoing total arterial myocardial revascularization (group 1) and conventional coronary surgery (group 2). The difference between the conventional and arterial groups was significant.
