Figure 1 Clinical end points and pairwise treatment comparisons for outcome after elective PCI based on hazard ratios. In addition, 95% confidence intervals (CI) and p values are presented. ABC = abciximab; ENOX = enoxaparin; UFH = unfractionated heparin. Composite efficacy end point = 30-day mortality, in-hospital myocardial infarction, or in-hospital refractory ischemia. Squares = ENOX versus UFH; triangles = ABC versus UFH.
