Dear Gabriel

Before you continue searching for small study effects I think a search
for possible moderators of the effects would be more worthwhile. If you
believe that the purpose of meta-analysis is to synthesise then the
spread of values you have calls that goal into question. If you believ
that the purpose of meta-analysis is to understand why effects differ
then searching for possible moderators must be more helpful than looking
for small study efects.

Ok, so in my case would it be better? to use for instance?either inverse
n or alternatively?variance,? is this correct?

Regarding the high variability in the range of my Fisher's z transformed
values you noticed before.
This variability could be due to the fact that the values come
from?different?geographies, use of varied treatments?and
different?methods?as well?
Is there a quantitative?measure or way that can help to give account of
such variability or explain?it?

Thanks a lot again for your advice and guidance.
Kind regards,
Gabriel
