Hi all,

1. Is it possible to create forest plots from precomputed data? I'm not sure what syntax to use (I'm unfamiliar with Stata - more familiar with SAS).

I have Study name, Year, Hedge's G, LCI, UCI, Weight. I also have these data for the Overall effect estimate (so don't need Stata to calculate the diamond).

I optimistically tried this command, which Stata rejected: . metan hg _LCI _UCI _WT, rr lcols (name year) xlabel (-2, -1.5, -1, -.05, 0, 0.5, 1, 1.5, 2)


2a. For the funnel plot, I used this command with precomputed data, with success: . metafunnel hg _SE, xtitle (Hedge's G) ytitle (Standard Error)

Looking at the funnel plot, some values seem off, but I might be imagining things. Is there any reason the above command would be incorrect (eg, maybe data needs to be transformed into a log scale)?

2b. I can't get the funnel plot to calculate the Egger regression test for funnel-plot asymmetry. Going off the syntax here: . metafunnel logor selogor, xtitle(Log odds ratio) ytitle(Standard error of log OR)
> egger

When I type variations of "> egger", the "unrecognised command" error comes up.

Many thanks for any help
