  1. Key: CECaT - Cost-effectiveness of functional cardiac testing in the diagnosis and management of coronary heart disease study, ACRE - Appropriateness for coronary revascularization study, PMR - Percutaneous myocardial revascularization compared to continued medical therapy study, TMR - Transmyocardial laser revascularization compared to continued medical therapy study, SPiRiT - Spinal cord stimulation (SCS) compared to PMR study, EVAD - Evaluation of ventricular assist devices (VAD) patients compared to patients on transplant waiting list (Tx WL) study, EQ-5D - Euroqol 5D, SD - standard deviation, CCS - Canadian Cardiovascular Society angina classification, NYHA - New York Heart Association angina classification
  2. *CCS class for all but EVAD groups. In the case where percentages do not sum to 100, it is due to missing values.
