Examples of a good funnel plot mat analysis. Funnel plots are commonly used in systematic reviews and meta analyses in the absence of publication bias it assumes that studies with high precision will be plotted near the average and studies with low precision will be spread evenly on both sides of the average creating a roughly funnel shaped distribution. This article describes how to interpret funnel plot asymmetry recommends appropriate tests and explains the implications for choice of meta analysis model. A funnel plot was presented figure. Funnel plot asymmetry should not be equated with publication bias because it has a number of other possible causes.

In a funnel plot the weight of each study the sample size or the inverse of the variance is plotted against the size of its treatment effect in a meta analysis. A funnel plot is a graph designed to check for the existence of publication bias. Asymmetric funnel plots may suggest publication bias. Statements a and b are true whereas c is false.

For the example funnel we ve chosen we ve included five main elements. Funnel plots and tests for funnel plot asymmetry have been widely used to examine bias in the results of meta analyses. Funnel plots and tests for funnel plot asymmetry have been widely used to examine bias in the results of meta analyses. Funnel plot for the meta analysis of the short term safety periprocedural mortality or stroke of carotid endarterectomy compared with carotid artery stenting which of the following statements if any are true.
