  • a Defined as peripheral artery disease and/or coronary artery disease.

  • b The risk factor ‘Labile INRs’ is not included in the HAS-BLED score as these data are not collected at baseline. As a result, the maximum HAS-BLED score at baseline is eight points (not nine). INR = international normalisation ratio. Q1 = quartile 1. Q3 = quartile 3. TIA = transient ischaemic attack.
