3. 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.

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.

6. 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.
