  1. MACE is a composite of first nonfatal myocardial infarction (MI), nonfatal stroke or cardiovascular death. Data shown are median (25th, 75th percentile) or n (%). Numbers nonmissing are shown separately in Additional file 1: Table S1. ACE: angiotensin-converting enzyme; ARB, angiotensin receptor blocker; CHF: congestive heart failure; COPD: chronic obstructive pulmonary disorder; eGFR: estimated glomerular filtration rate; HDL-c: high-density lipoprotein cholesterol; LDL-c: low-density lipoprotein cholesterol; NSAIDs: nonsteroidal anti-inflammatory drugs; PCI: percutaneous coronary intervention; TIA: transient ischemic attack; UACR: urine albumin-to-creatinine ratio; VKA: vitamin K antagonist
  2. *P-values are calculated from univariable Cox proportional hazards regression models; multiple imputation was used when missing data were present
  3. †When relationships between continuous variables and MACE are non-linear the p-value is for the model containing two piecewise linear splines
