Hi Michael,
Would it not be nonsensical to have multiple effects from the same article in the funnel plot though?
With the Egger?s regression I was able to accommodate the fact that their is nonindependence of the effects, but am unsure how to proceed with a funnel plot.

Dear Dylan
Perhaps I misunderstand you but if you have the data for a regression
type test like Egger's do you not just plot that? The funnel() function
in metafor does that and I am sure equivalent solutions can be found in
meta and many other packages.
