2. Fig 1
Scatterplots demonstrating the correlation between The Society of Thoracic Surgeons (STS) risk score (x-axis) and the European System for Cardiac Operative Risk Evaluation (EuroSCORE) I and II (y-axis). Blue circles indicate STS score and EuroSCORE II; red circles indicate STS score and EuroSCORE I.

3. Fig 2
Receiver-operating characteristic curves showing the discriminative ability for each risk score by surgery group: (A) coronary artery bypass graft; (B) aortic valve; (C) mitral valve; and (D) coronary artery bypass graft plus valve. Red lines indicate The Society of Thoracic Surgeons risk model; dark blue lines indicate European System for Cardiac Operative Risk Evaluation (EuroSCORE) II risk model; light blue lines indicate EuroSCORE I risk model; and black lines are reference lines.
