A Meta-Analysis of Resveratrol Protects against Myocardial Ischemia/Reperfusion Injury: Evidence from Small Animal Studies and Insight into Molecular Mechanisms

Figure 3

Funnel plot for assessment of publication bias for the infarct size in vivo (a) and ex vivo (b). Funnel plots were scatter plots (blue points) of the effect sizes of the included studies versus a measure of their precision usually standard error. The funnel plot appeared to have minimal asymmetry in (a); however, it was symmetrical in (b).
