  1. *CABG also includes SCS (spinal cord stimulation) and laser (percutaneous or transmyocardial laser revascularization ) treatments. Reference category - Post CABG.
  2. **Reference category, class IV.
  3. ***All SAQ score parameter estimates are for a one point increase in the score for the given scale.
  4. Key: MM = medical management, PCI = balloon angioplasty ± stent, CABG = coronary artery bypass graft, ETT = exercise treadmill time, CCS = Canadian Cardiovascular Society Angina Classification, ECS = exertional capacity scale, ASS = anginal stability scale, ACRE = Appropriateness for coronary revascularization, AFS = anginal frequency scale, DPS = disease perception scale, TSS = treatment satisfaction scale
