  1. Notes.
  2. 1. PTCA = percutaneous transluminal coronary angioplasty; CABG = coronary artery bypass grafting; CARP = coronary artery revascularisation procedure (PTCA or CABG).
  3. 2. SES Q1 is most disadvantaged quintile.
  4. 3. SES Q1, n = 469; SES Q2, n = 417; SES Q3, n = 343; SES Q4, n = 327; SES Q5, n = 304.
  5. 4. Cumulative probability of a procedure at one year was estimated using the Kaplan-Meier estimator.
  6. 5. Because some patients had both CABG and PTCA on the same day, the % of patients undergoing first CARP procedures does not equal % PTCA plus % CABG.
  7. 6. Hazard ratios estimated using Cox regression and adjusted for age in Model 1, as well as other confounding variables (country of birth, Aboriginal/Torres Strait Islander status, marital status, comorbidities, area of residence and hospital area) in Model 2 and confounding and mediating variables (private insurance and private hospital) in Model 3.
