Dear Agge,
some suggestions:

1) type -search metan- from within Stata (my release 9.2/SE);

2) take a look at the following textbooks: 
a) Michael Borenstein, Larry V. Hedges, Julian P. T. Higgins, and Hannah R.
Rothstein. Introduction to Meta-Analysis. Wiley, 2009.  
Comment from the Stata technical group (please, see
Meta-analysis has gained increasing popularity since the early 1990s as a
way to synthesize the results from separate studies. It is widely used in
the medical sciences, education, and business. This text is both complete
and current, and is ideal for researchers wanting a conceptual treatment of
the methodology. A chapter on statistical software for performing
meta-analysis (including how to do so in Stata) is also included;
b) Sutton AJ, Abrams KR, Jones DR, Sheldon TA, Song F. Methosùds for
meta-analysis in medical research. Wiley, 2000.

3) search the web for:
a) "power AND meta-analysis";
b) "power AND meta-analysis AND Stata".

Sorry I cannot be more helpful.
Kind Regards,
-----Messaggio originale-----

Dear Carlo,

Thank you very much for your response and suggestions. It is much

Since posted to the list, I have done a chi2 test  to see if there is,
for example, a significant relationship between mentioning (or not)
the famework and the type of a journal.
After some thinking, I am planning to do a meta-analysis and would
appreciate if you (or anybody from the list) advise me how to do a
power analysis for the meta-analysis.

So sorry for any confusions, but I am at a finding the right tool stage.
Your suggestions will be much appreciated.
