Figure 3 Kaplan-Meier event-free survival curves by summed difference score (SDS) categories. Patients with an SDS of 0 (n = 242) had significantly lower event rates than patients with an SDS of 1 to 4 (n = 49; p = 0.03); these patients had significantly lower event rates than patients with SDS >4 (n = 16; p = 0.005). Note the significant differences in outcome between patients with no, mild, and moderate to severe ischemia, as defined by SDS. MPS = myocardial perfusion SPECT.
