-Here is another example of a contour-enhanced funnel plot (Peters et al., 2008) (see [[plots:​contour_enhanced_funnel_plot|here]] for a brief discussion of the idea behind such plots). This one is a very close re-creation of Figure 2(b) from Peters et al. (2008). Note that the values for ''​ylim''​ technically have to be greater than 0 when using the inverse standard error on the y-axis, but we can get essentially the same limits by using a very small value for the lower limit.+Here is another example of a contour-enhanced funnel plot (Peters et al., 2008) (see [[plots:​contour_enhanced_funnel_plot|here]] for a brief discussion of the idea behind such plots).

Also, the dataset used by Peters et al. (2008) contains an extra study, which isn't included in the Cochrane review by Graves et al. (2010).
