Dear all,

I have performed a meta-analysis using the 'meta' command and would like
to outfile the odds ratio, lower confidence limit, upper confidence limit
and fixed and random weights, for each individual study, to a raw file.
What are the names of the system variables for the odds ratio, lower ci,
upper ci and the weights?  I intend to generate variables from these
system variables, collapse, and outfile.  Is that correct?
Dear Andrea,

It's probably going to be a little easier if you switch to use -metan- instead of -meta- as -metan- generates new variables containing the weights and CI limits. The most recent version of -metan- accepts the same input variables in the same order as -meta- i.e. effect estimates and standard errors. This is version 1.81 and is obtained by typing -ssc intall metaaggr, replace-. Full documentation including names of the variables left behind is available at <http://www.ihs.ox.ac.uk/csm/metan/metan_updates.pdf>

How you best handle the variables afterwards depends on what you want to use them for which you know better than us.

Best wishes,
Roger.
