  • Standard covariates=age, male sex, obesity, educational level, coronary risk factors (hypertension, dyslipidaemia, diabetes mellitus).

  • Model 1=standard covariates+previous MI.

  • Model 2=standard covariates+previous PCI.

  • BMI, body mass index; MI, myocardial infarction; PCI, percutaneous coronary intervention.
