Figure 1 Protocol-directed angiography schedule. Each patient was randomly allocated one of five schedule dates: 1, 2 5, 7, and 10 (range) years. Angiograms were weighted to latter part of 10-year study. The Journal of Thoracic and Cardiovascular Surgery 2003 125, 1363-1370DOI: (10.1016/S0022-5223(02)73241-8)
