Non-vitamin K antagonist oral anticoagulants versus warfarin in AF patients ≥ 85 years.

For the efficacy, NOACs were associated with a comparable or lower risk of ischaemic stroke compared to warfarin. For adverse events, NOACs were associated with a lower risk of all-cause mortality and composite adverse events. In the elderly AF population, NOACs could be a more favourable choice for stroke prevention.
