SVG occlusion	27.7	21.0	1.36 (1.13, 1.64)	0.002	1.30 (1.08, 157)	0.009
Grafts with “good” target arteries—per graft angiographic end point, n	431	2284
SVG stenosis ≥75%	29.2	20.8	1.49 (1.20, 1.87)	0.001	1.40 (1.13, 1.76)	0.006
SVG occlusion	27.0	18.0	1.64 (1.30, 2.06)	<0.001	1.53 (1.21, 1.93)	0.001

Values are percentages unless otherwise indicated.

^*Adjusted for weight, duration of surgery, harvest technique, target-vessel quality, and graft quality.

m-SVG indicates saphenous vein graft with >1 distal target; OR, odds ratio; CI, confidence interval; and SVG, saphenous vein graft.
