RE: st: RE: Graphing limitations / questions

Thanks Tom. It took me some time to understand what you are trying to say in 
relation to my query but unfortunately I still do not understand what you 
are trying to get at. Please bear with me.

I do understand (and know) that metan command would produce effect size and 
its confidence interval. However, what I am hoping to achieve (and I've to 
use Arcus package at the moment to accomplish it) is to generate some sort 
of a forest plot of various OR's (and their respective CI's) generated from 
several metan runs, for visual comparison in a single diagram. I am 
currentlly looking at the metan ado file to see whether there is something 
that i can use to generate the forest plot that I want (I suspect none but 
will let listers know).

Kind regards,
bw
