Dear Carlo,

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

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.
