Figure 6

Forest plot depicting hazard ratios of several covariates. Statistical significance () marked with a star. A hazard ratio <1 illustrates a protective effect on patient outcome, whereas a hazard ratio >1 represents a negative effect. ACS = acute coronary syndrome; EF = ejection fraction; PAOD = peripheral artery occlusive disease, EPD = embolic protection device; CABG = coronary artery bypass graft; TIMI = thrombolysis in myocardial infarction; and SVG = saphenous vein graft.
