Figure 4 Scattergraph shows raw data of all luminal percent area stenoses correspondent to each mean reference percent area stenosis. The dotted line and solid line (Y = –0.21X + 68.0) indicate the cutoff value and line that discriminates the SPECT (+) group from the SPECT (–) group. SPECT, single-photon emission computed tomography. Open circle = SPECT (+); solid circle = SPECT (–).
