Meta Analysis Comparative Study
Relative efficacy and safety of non-Vitamin K oral anticoagulants for non-valvular atrial fibrillation: Network meta-analysis comparing apixaban, dabigatran, rivaroxaban and edoxaban in three patient subgroups.
Stroke is the most serious clinical consequence of atrial fibrillation, which is the most common cardiac arrhythmia. Non-vitamin K antagonist oral anticoagulants (NOACs) have emerged as efficacious, safe and convenient stroke prevention agents. This updated network meta-analysis focused on the relative efficacy and safety of apixaban compared with dabigatran, rivaroxaban and edoxaban for stroke prevention in (i) patients with CHADS2 score ≥ 2, (ii) secondary stroke prevention, and (iii) patients with high quality anticoagulation control with warfarin. ⋯ Among the NOACs, apixaban offered the most favourable efficacy and safety profile in the overall patient population as well as in the three subgroups investigated.
