[R-meta] correlational meta-analysis

[Cátia Ferreira De Oliveira]

Dear all,

I hope you are well.
When conducting a correlational meta-analysis with multiple effect sizes
per study, would the variance-covariance matrix represent the correlations
between those effect sizes, i.e. the correlation of the correlation
coefficients? If so, is it fair to assume that the correlation of these
effect sizes has to be necessarily inferior to the original correlations?

Thank you!

Best wishes,

Catia
