Dataset from Post Coronary Artery Bypass Graft (CABG) Study

To determine the relative effectiveness of moderate versus more aggressive lipid lowering, and of low dose anticoagulation versus placebo, in delaying saphenous vein coronary bypass graft atherosclerosis and preventing occlusion of saphenous grafts of patients with saphenous vein coronary bypass grafts placed 1 to 11 years previously.

本数据集旨在明确两项对比干预的相对疗效：其一为中等强度与强化降脂治疗（lipid lowering），其二为低剂量抗凝治疗（anticoagulation）与安慰剂（placebo），以评估二者在延缓1~11年前接受大隐静脉冠状动脉旁路移植术的患者所植入的大隐静脉冠状动脉旁路移植物（saphenous vein coronary bypass graft）的动脉粥样硬化（atherosclerosis）进展，并预防该类移植物闭塞方面的作用。
