  1. Odds ratios; p-values are presented.
  2. a CAD: CAD vs no CAD (after angiography).
  3. b LVEF: Left ventricular ejection fraction. Nonlinear relationships entered, differences for selected LVEF intervals are presented.
  4. Significantly associated to CCS (**), and to NYHA (II-IV vs. 0–I, ***). Nonlinearity: Significant for NYHA (II-IV vs. 0–I, **).
  5. c CCS: Canadian Cardiovascular Society Angina Classification, 0 (no angina) to IV (worst, not present in our data).
  6. d NYHA: New York Hear Association Dyspnoea Classification, 0 (no dyspnoea) to IV (worst). 0 and I, and III and IV, collapsed in our data due to small numbers
  7. t All two-way interactions, overall p-value. Not feasible for NYHA, feasible after a few simplifications if necessary
