Figure 1 Graph showing on a logarithmic scale the odds ratios for clinical events and angiographic restenosis associated with the presence of the IL-1RN*2 allele for the entire population (left panel) and patients <60 years (right panel). ILRN = interleukin-1 receptor antagonist gene; MI = myocardial infarction; TVR = target vessel revascularization.

Figure 2 Bar graph showing the decrease in the incidence of restenosis and TVR in patients <60 years with the increase in the number of IL-1RN*2 alleles. ILRN = interleukin-1 receptor antagonist gene; TVR = target vessel revascularization.
