Fig. 5From: Frequency of atrial thrombus formation in patients with atrial fibrillation under treatment with non-vitamin K oral anticoagulants in comparison to vitamin K antagonists: a systematic review and meta-analysisFunnel plots showing Peto ORs (left) and RDs (right); the left plot shows only three values since one RCT had no events in both arms, so that Peto ORs could not be estimated; the funnel plot of the RRs was very similar to that of the Peto ORs, and is therefore not shown hereBack to article page
