a Forest plot for early vein graft occlusion at median 1 year reported follow-up between No Touch technique and Conventional SVG harvesting technique. The graft occlusion results from the current study refer to the study saphenous veins according to the allocated treatment. b Forest plot for early vein graft occlusion or significant stenosis (> 50% narrowing of lumen) at median 1 year reported follow-up between No Touch technique and Conventional SVG harvesting technique.
