FIGURE 1. Patient Flow in the Original FREEDOM Trial and the FREEDOM Follow-On Study.

FIGURE 1

After the completion of the initial FREEDOM (Future Revascularization Evaluation in Patients with Diabetes Mellitus: Optimal Management of Multivessel Disease) trial, centers and patients were invited to participate in the FREEDOM Follow-On study. A total of 25 centers agreed to participate, resulting in a population of 943 patients. Excluding patients who died (n = 104), withdrew consent, or were lost to follow-up (n = 66) during the original FREEDOM follow-up, 773 patients were available to be followed. In the end, follow-up information was obtained for 766 patients (99% of the patients in the FREEDOM Follow-On). The expression “early terminate” in the bottom boxes refers to subjects who were lost to follow-up or withdrew consent before the beginning of the FREEDOM Follow-On study. As observed in the figure, there were numerical differences in the numbers of early termination and missing death status between the 2 treatment groups. CABG = coronary artery bypass grafting; PCI = percutaneous coronary intervention.
