Figure 2 Funnel Plot of the Meta-Analysis
Review: statins versus placebo or control regimen for the end point of first episode (new-onset or post-operative) or recurrence of atrial fibrillation (AF). Funnel plot allows assessment of publication bias. Bias is suspected if the plots are asymmetric on each side of the dashed line. Present plot shows no clear evidence of bias. OR = odds ratio.
