Figure 3. Saphenous Vein Graft Failure in Subgroups.

Subgroup analyses for harvesting technique and target vessel territory could not be performed due to the limited number of events in the endoscopic-harvesting group and left anterior descending coronary artery territory group. Treatment duration varied in 1 trial only.

^aAdjusted by trial.

^bSelf-reported diagnosis, elevated hemoglobin A_1c levels, or active therapy. Definitions varied by trial.

^cIncludes ST-segment elevation myocardial infarction, non–ST-segment elevation ACS, or unstable angina. Definitions varied by trial.

^dDefined as saphenous vein grafts with more than 1 anastomosis.

Includes patients from the TAP-CABG,⁸ DACAB,⁹ and POPular CABG¹⁰ trials. See the Methods section for the full names of the studies.

ACS indicates acute coronary syndrome; CPB, cardiopulmonary bypass; DAPT, dual antiplatelet therapy; SVG, saphenous vein graft.
