title: Non-vitamin K antagonist oral anticoagulants in atrial fibrillation patients with chronic kidney disease: A systematic review and network meta-analysis.
abstract: BACKGROUND
  Currently there is lack of head-to-head comparisons between different Non-Vitamin K Antagonist Oral Anticoagulants (NOACs), especially in more risky subgroups, as those with chronic kidney disease (CKD).
  
  
  METHODS
  We assessed the relative efficacy and safety of the four NOACs on the market in a systematic review and network meta-analysis of patients with atrial fibrillation (AF) and moderate CKD enrolled in the phase 3 randomized trials. A Bayesian framework was used to perform the network meta-analysis. Treatment hierarchy was assessed by surface under the cumulative ranking (SUCRA) curves.
  
  
  RESULTS
  Five randomized trials including 13,878 AF patients with moderate CKD were identified. Full/Single dose NOACs were associated with significant reductions in the odds of stroke/systemic embolism (odd ratio [OR] 0.79, 95% credible intervals [CrI] 0.67-0.94) and major bleeding (OR 0.74, 95% CrI 0.65-0.86) compared with Warfarin. Dabigatran 150 had the highest probability of being ranked first with respect to efficacy (SUCRA 0.96), whereas Apixaban had the second highest (SUCRA 0.67); Dabigatran 110, Rivaroxaban and Edoxaban High-Dose showed similar probabilities of being ranked first for efficacy (SUCRA 0.54, 0.53, 0.51, respectively); with respect to safety, only Apixaban and Edoxaban High Dose had a probability >50% of being ranked first (SUCRA 0.84 and 0.61, respectively).
  
  
  CONCLUSIONS
  Indirect comparisons generated the hypothesis that Apixaban and Edoxaban High-Dose might be more likely associated with a better net clinical profile in AF patients with moderate CKD. These findings may potentially guide physicians in selecting the most appropriate NOAC for each patient, while waiting for dedicated evidences.
