will the same program help to plot summary statistics in meta
analysis.  Here the x axis would be OR and 95% CI and Y axis is the
different variables.  This is not the actual forest plot which can be
easily produced by the metan program.  For example- when performing
meta-analysis, suppose you perform subgroup analyses for different
categories like age, sex etc...can one plot the OR and 95% CI using
the program which you suggested but flipping the axis over.

Roger Newson's user-written -eclplot- package, downloadable by SSC, should
be just the solution for you. Try this, which is used in conjunction with
two more of Roger's user-written packages, -parmby- and -sencode-:

. webuse union, clear
. parmby "xi:logit union age i.grade south black, or", label norestore
. sencode label, gene(parmlab)
. eclplot estimate min95 max95 parmlab, hori eplot(scatter)

It's not the most sensible example, for sure, but this seem to do exactly
what you want. Hope that helps.

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
