Forest plot showing hazard ratios for angiography and revascularisation by education level (low or intermediate; high = reference group), with (Model 4, [orange dot] and without (Model 3, [blue dot])) adjustment for private health insurance. Sample size = 4454 AMI patients; 4348 angina patients. Education level defined as low (no school certificate/qualifications), intermediate (school or leaving certificate/trade/apprenticeship/diploma/other certificate) and high (university degree or higher). Revascularisation refers to percutaneous coronary intervention or coronary artery bypass grafting. Model 3: HRs fully adjusted for age, sex, remoteness, country of birth, BMI, physical functioning and comorbidities. Model 4: HRs adjusted for covariates in Model 3 + private health insurance status. HR = hazard ratio; Error bars depict 95% confidence intervals
