Systematic Review: The Comparative Effectiveness of Percutaneous Coronary Interventions and Coronary Artery Bypass Graft Surgery

Figure 3.
Figure 3. Five-year survival with balloon angioplasty or stents versus coronary artery bypass grafting (CABG) in patients with multivessel disease (MVD).

The size of each box is proportional to the sample size of the trial. Bars represent 95% CIs. The I2 statistic for 5-year survival was 10 among MVD trials using balloon angioplasty and <1.0 among trials using stents. ARTS = Arterial Revascularization Therapies Study; AWESOME = Angina with Extremely Serious Operative Mortality Evaluation; BARI = Bypass Angioplasty Revascularization Investigation; BMS = bare-metal stent; CABG = coronary artery bypass grafting; EAST = Emory Angioplasty versus Surgery Trial; ERACI = Argentine randomized trial of percutaneous transluminal coronary angioplasty versus coronary artery bypass surgery in multivessel disease; GABI = German Angioplasty Bypass Surgery Investigation; MASS = Medicine, Angioplasty, or Surgery Study; PCI = percutaneous coronary intervention; RITA = Randomized Intervention Treatment of Angina. *Survival data were abstracted from Kaplan–Meier curves.
