Fig 1 Receiver operating characteristic (ROC) curves for the four models. The diagonal line represents no discriminatory power (area under the curve 0.50). (ACEF = age, creatinine, and ejection fraction; EuroSCORE = European System for Cardiac Operative Risk Evaluation; STS = The Society of Thoracic Surgeons.)

Fig 2 Calibration plots of the 4 scores analyzed by means of smooth nonparametric fit using the lowess algorithm. The diagonal line represents the perfect calibration. A: Calibration of ACEF score. B: Calibration of EuroSCORE II. C: Calibration of logistic EuroSCORE. D: Calibration of STS score. (ACEF = age, creatinine, and ejection fraction; EuroSCORE = European System for Cardiac Operative Risk Evaluation; STS = The Society of Thoracic Surgeons.)
