Analysis of area under the curve (AUC). (a) Overall (AUC for GMPI, CT-AC, and NAC: 0.738 vs. 0.698 vs. 0.654#). (b) Right CAD (AUC for GMPI, CT-AC, and NAC: 0.733 vs. 0.596 vs. 0.624#,&). (c) Men (AUC for GMPI, CT-AC, and NAC: 0.754 vs. 0.681 vs. 0.563*,#,&). (d) Overweight individuals (AUC for GMPI, CT-AC, and NAC: 0.730 vs. 0.686 vs. 0.600#). *P<0.05 for NAC and CT-AC, #P<0.05 for NAC and GMPI, and &P<0.05 for CT-AC and GMPI. CAD, coronary artery disease; CT-AC, CT attenuation correction; GMPI, gated myocardial perfusion imaging; NAC, nonattenuation correction.
