Figure 2 Outcome comparison between non-vitamin K oral anticoagulants (NOACs) and vitamin K antagonists (VKAs) in patients with atrial fibrillation undergoing cardioversion. Forest plot with individual and summary estimates of the risk ratio and 95% confidence interval (CI) of stroke/systemic embolism. A random-effects model was applied to estimate risk ratio and 95% CI. Squares and diamond sizes are proportional to study weight. The American Journal of Medicine , e2DOI: ( /j.amjmed ) Copyright © 2016 Elsevier Inc. Terms and Conditions

Figure 3 Outcome comparison between non-vitamin K oral anticoagulants (NOACs) and vitamin K antagonists (VKAs) in patients with atrial fibrillation undergoing cardioversion. Forest plot with individual and summary estimates of the risk ratio and 95% confidence interval (CI) of major bleeding. A random-effect model was applied to estimate risk ratio and 95% CI. Squares and diamond sizes are proportional to study weight. The American Journal of Medicine , e2DOI: ( /j.amjmed ) Copyright © 2016 Elsevier Inc. Terms and Conditions

Supplementary Figure 1 Assessment of publication bias. Begg's funnel plot of studies according to the risk ratio (RR) of stroke/systemic embolism (A) and major bleeding (B) vs the standard error of risk ratio.

Supplementary Figure 2 Jackknife sensitivity analysis. To evaluate whether the summary estimate of the effect could have been significantly affected by a single study, pooled estimates for stroke/systemic embolism (A) and major bleeding (B) were recalculated, using a random-effects model, by omitting one study at a time. Each line represents a reanalysis of the data with exclusion of one study at a time to assess the influence of this particular study on the overall result.
