funnel plot
funnel plot
a graphic method of detecting publication bias. The estimate of risk derived from a set of epidemiologic studies used in a metaanalysis is plotted against sample size. If there is no publication bias, the plot is funnel-shaped; if studies giving significant results are more likely to be published than negative studies, the plot is asymmetric.
