Fig. 1. Average of resampled ROC curves with box plot confidence intervals comparing the discrimination of EuroSCORE alone with models including preoperative (Pre cTnI) and postoperative cardiac troponin I (Post cTnI) in predicting both MACE (A and B ) and in-hospital mortality (D and E ). Panels C and F represent comparisons of EuroSCORE + Pre cTnI and EuroSCORE + Pre/Post cTnI to predict MACE and in-hospital mortality, respectively. P values represent the significance of the comparisons of areas under the ROC curves for the two presented ROC curves in each panel. EuroSCORE = The European System for Cardiac Operative Risk Evaluation; MACE = nonfatal major adverse cardiac events; ROC = receiver operating characteristic.
