Figure 2 Estimated change in the five-year relative risk of non-fatal myocardial infarction or CHD death associated with mean LDL-C reduction for the diet, bile-acid sequestrant, surgery, and statin trials (dashed line) along with the 95% probability interval (dotted line). The solid line has a slope = 1. The crude risk estimates from the individual studies are plotted along with their associated 95% confidence intervals. The Sydney (26) trial is not shown but was included in the analysis. Statin trials are designated by the boldface symbols. CHD = coronary heart disease; LDL-C = low-density lipoprotein cholesterol. Study acronyms: MRC = Medical Research Council; LRC = Lipid Research Clinics; NHLBI = National Heart, Lung, and Blood Institute; POSCH = Program on the Surgical Control of the Hyperlipidemias; 4S = Scandinavian Simvastatin Survival Study; WOSCOPS = West of Scotland Coronary Prevention Study; CARE = Cholesterol and Recurrent Events study; LIPID = Long-Term Intervention with Pravastatin in Ischemic Disease; AF/TexCAPS = Air Force/Texas Coronary Atherosclerosis Prevention Study; HPS = Heart Protection Study; ALERT = Assessment of LEscol in Renal Transplantation; PROSPER = PROspective Study of Pravastatin in the Elderly at Risk; ASCOT-LLA = Anglo-Scandinavian Cardiac Outcomes Trial–Lipid Lowering Arm; CARDS = Collaborative Atorvastatin Diabetes Study.
