Is there a "do" file for metaparm or eclplot.
thanks,

Yes, -eclplot- can plot meta-analyses on subgroups. A useful program for
preparing the data for this plot might be -metaparm-, which is now part
of the -parmest- package, downloadable from SSC. And -eclplot- can also
do vertical or horizontal CI plots, and use a -by()- option to produce
multiple plots arrayed on a page.

An example of a multiple plot, and a Cochrane forest plot produced using
-eclplot- and -metaparm-, is given in my presentation to the 2006 German
Stata User Meeting at Mannheim. Files for this presentation can be
downloaded from

I hope this helps.

Best wishes

I'm an alleged political scientist, so - almost by definition - I know
nothing about meta-analysis. Perhaps another Statalister can field this
query if s/he deems it's within their competence.

Anyway, I don't think it's cricket (!) to respond, "Well, yes, that's
all
very well, but it doesn't do _this_, does it?" It wasn't intended to. It
was intended to do what Bill specifically asked it to do, and he hasn't
yet returned to say that it doesn't. (I know it does because I tested
the
code successfully on one of Stata's 'toy' datasets before posting it.)

Whereever you go and whatever you do, just remember this. No matter how
many like you, admire you, love you or adore you, the number of people
turning up to your funeral will be largely determined by local weather
conditions.
