Comparison of European System for Cardiac Operative Risk Evaluation (EuroSCORE) and the Society of Thoracic Surgeons(STS) score for risk prediction in Indian patients undergoing coronary artery bypass grafting.

Both the EuroSCORE and the STS scores had satisfactory and similar discriminatory power. However, in the Indian population, while the EuroSCORE II overestimated mortality, the STS score underestimated it to a similar degree of error.
