  • *Adjusted for age at index date, sex and left ventricular end-diastolic dimension.

  • †Additionally adjusted for baseline values of: systolic blood pressure, diastolic blood pressure, body mass index, total and HDL cholesterol, smoking status and left ventricular end-diastolic dimension. Time dependent covariates include: blood pressure lowering drugs, history of myocardial infarction, presence of heart failure, prevalent diabetes.

  • HDL, high-density lipoprotein; n, number of atrial fibrillation cases; NA, not applicable; NSAID, non-steroidal anti-inflammatory drug.
