* The ICER is a comparison of the GP with ECG compared to GP without an ECG, with the value on the left corresponding with the leftward most value in the tested range. All ICERs are rounded to the nearest dollar.
† "Cost-saving" here is defined as the ECG intervention costing less and increasing QALYs gained compared to no ECG.
ACS = acute coronary syndrome, ECG = electrocardiogram, ICER = incremental cost-effectiveness ratio, QALY = quality adjusted life year
