Figure 3 Graph showing the strength (i.e., chi-square value) of the logistic regression models for thrombotic events and angiographic restenosis. Each top solid bar is for the full model, including clinical, lesion-related, and procedural variables; the other open bars are for the respective partial models. The graph illustrates the dominant influence of clinical factors on thrombotic events, as opposed to the dominant influence of procedural factors on restenosis.
