Thank you Tom for your advice. I checked metan's help file as well as the STB. The command does not allow metan of odds ratios and their CI's - if this is what you mean by creating a new datasets, i.e. datasets of summary odds ratios point estimates and their respective CI's.

Regarding DIY - wish I am able to. On a few occasions I have tinkered with the codes but futile were my efforts. So I adopted a pragmatic approach - using two different softwares to do what I need to do. Nevertheless if ever I can crack this on Stata, I will post it to the list.

Kind regards,
bw

One can always create a new dataset of the summary point
estimates and CI's and re-analyse those with -metan- to
generate a "comparison" forest plot.  The summary stats
are returned after a -metan- run or can be hand entered.

-metan- is a user-contributed program and, as such, does
not benefit from direct StataCorp support.  One can, though,
work out the necessary code for the wanted bells and whistles
and propose it to the author for inclusion in his work...
Or you can clone it, add the bits to your version, then
consider contributing and supporting (at whatever level you
are willing to do) your version for the benefit of all.
....or, StataCorp could take on the project of providing a
supported suite of meta-analysis commands ...but I'd advise
not holding your breath while waiting!

Tom
