  • Diabetes, 0 = no and 1 = yes; male, 0 = women and 1 = men; smoker, 0 = no and 1 = yes.

  • *The cut-off value of these quantitative variables (age, LVEF, SSS, SDS, METs, and mm ST depression) was calculated by means of ROC analysis.

  • †Cox-Snell r2: 0.037; Nagelkerke r2: 0.168; Hosmer and Lemeshow Test: χ2: 2,705; p = 0.168.

  • ‡Cox-Snell r2: 0.059; Nagelkerke r2: 0.165; Hosmer and Lemeshow Test: χ2: 2,150; p = 0.976.

  • LVEF, left ventricular ejection fraction; ROC, receiver operating characteristic; SDS, summed difference score; SSS, summed stress score.
