Figure 2 Patients undergoing transcatheter aortic valve replacement. A, Calibration plots of the Society of Thoracic Surgeons (STS) scores for 30-day/in-hospital mortality. Perfect calibration is represented by the dashed line whereby observed equals predicted probability of mortality (X = Y, slope = 1, intercept = 0). B, Calibration plots of the logistic European System for Cardiac Operative Risk Evaluation (LES) score for 30-day/in-hospital mortality. Perfect calibration is represented by the dashed line whereby observed equals predicted probability of mortality (X = Y, slope = 1, intercept = 0). C, Calibration plots of the STS scores for 30-day/in-hospital morality analyzed by tertiles. Perfect calibration is represented by the dashed line whereby observed equals predicted probability of mortality (X = Y, slope = 1, intercept = 0). D, Calibration plots of the LES scores for 30-day/in-hospital mortality analyzed by tertiles. Perfect calibration is represented by the dashed line whereby observed equals predicted probability of mortality (X = Y, slope = 1, intercept = 0). E, Calibration plots for the STS scores for 1-year mortality. Perfect calibration is represented by the dashed line whereby observed equals predicted probability of mortality (X = Y, slope = 1, intercept = 0). F, Calibration plots for the LES for 1-year mortality.
