Hi

I'm using metafunnel in Stata 15.1 to plot funnel plots for a meta-analysis I'm undertaking but not all the data points are appearing, and I'm a bit stumped as to why.

There are 10 data points eligible for inclusion in the meta-analysis, and these are appearing fine in the forest plot. (I have anonymised the studies for confidentiality reasons)

Code:
metan metan_lneffect metan_lnlci metan_lnuci, eform random label(namevar=dpid) nobox
Array
However, when I run the command

Code:
metafunnel metan_lneffect metan_lnlci metan_lnuci, eform forcenull
Array

none of the studies appear on the funnel plot. I'm having a similar problem with meta-analyses of other sections of same dataset, with only a subset of the studies appearing.

All of these data points have a valid estimate of effect, lower CI and upper CI, so I'm struggling a bit to see where I'm going wrong, and I haven't been able to find any examples of others having similar problems.

No doubt my error is something extremely basic, but it's got to the point where I would really welcome some outside help - any advice very gratefully received.
