  • * Multivariate models were adjusted for age (continuous), baseline history of comorbid medical condition (hypertension, diabetes, hyperlipidaemia and chronic obstructive pulmonary disease) (yes, no), baseline Charlson comorbidity score (continuous) and monthly prescription drug use (non-steroidal anti-inflammatory drug, diuretic, statin, anticoagulant, aspirin, hormone replacement therapy and glucocorticoid) (yes, no) as time-varying covariates.

  • AMI, acute myocardial infarction; PY, person-years; RR, relative risk.
