Non-vitamin K antagonist oral anticoagulants compared with warfarin at different levels of INR control in atrial fibrillation: A meta-analysis of randomized trials
The efficacy and safety of warfarin for stroke prevention in atrial fibrillation (AF) depend on the time in the therapeutic range (TTR) with an international normalised ratio (INR) of 2.0 –3.0. This meta-analysis focused the relative efficacy and safety of non-VKA oral anticoagulants (NOAC) compared with warfarin at different thresholds of centre's TTR (cTTR).
