  • Significance estimates for age-adjusted comparison between those with and without T2D and not using statins (no) and statin users (yes): *p<0.05; **p<0.01; ***p<0.001.

  • * Hypertensive includes those with systolic blood pressure (BP) of >140 mm Hg or diastolic BP of >90 mm Hg, or on hypertensive medication.

  • Prevalence from history of myocardial infarction, percutaneous coronary intervention, and coronary-artery bypass grafting in hospital records.
